Metabox in the front-end

Hi, I am trying to set up a private zone on the front end for clients and I am using cmb2 to add data from each of them.

Create a custom post called “perfiles”.

function post_perfiles(){
 $labels = array(
 'name'               => _x('Perfiles', 'divi'),
 'singular_name'      => _x('Perfil', 'post type singular name', 'divi'),
 'menu_name'          => _x('Perfiles', 'admin menu', 'divi'),
 'name_admin_bar'     => _x('Perfiles', 'add new on admin bar', 'divi'),
 'add_new'            => _x('A?adir Perfil', 'book', 'divi'),
 'add_new_item'       => __('A?adir Nuevo Perfil', 'divi'),
 'new_item'           => __('Nuevos Perfiles', 'divi'),
 'edit_item'          => __('Editar Perfil', 'divi'),
 'view_item'          => __('Ver Perfil', 'divi'),
 'all_items'          => __('Todos los Perfiles', 'divi'),
 'search_items'       => __('Buscar Perfiles', 'divi'),
 'parent_item_colon'  => __('Parent Perfiles:', 'divi'),
 'not_found'          => __('No se han encontrado Perfiles', 'divi'),
 'not_found_in_trash' => __('No se han encontrado Perfiles en la papelera', 'divi')
 );
 
 $args = array(
     'labels'             => $labels,
     'description'        => __('Description.', 'divi'),
     'public'             => true,
     'publicly_queryable' => true,
     'show_ui'            => true,
     'show_in_menu'       => true,
     'query_var'          => true,
     'rewrite'            => array('slug' => 'perfiles'),
     'capability_type'    => 'post',
     'has_archive'        => true,
     'hierarchical'       => false,
     'menu_position'      => 4,
     'supports'           => array('title', 'editor', 'author', 'thumbnail'),
 );
 register_post_type('perfiles', $args);
}
add_action('init', 'post_perfiles');

function mis_taxonomias_perfiles(){
    //Tipo de Perfil
    $labels = array(
     'name' => _x('Tipo de Perfil', 'taxonomy general name', 'divi'),
     'singular_name' => _x('Tipo de Perfil', 'taxonomy_general_name', 'divi'),
     'search_items' => __('Buscar Tipo de Perfil', 'divi'),
     'all_items' => __('Todos los Tipos de Perfiles', 'divi'),
     'parent_item' => __('Padre Tipo de Perfil', 'divi'),
     'parent_item_colon' => __('Padre Tipo de Perfil', 'divi'),
     'edit_item' => __('Editar Tipo de Perfil', 'divi'),
     'update_item' => __('Actualizar Tipo de Perfil', 'divi'),
     'add_new_item' => __('A?adir Nuevo Perfil', 'divi'),
     'new_item_name' => __('Nuevo Tipo de Perfil', 'divi'),
     'menu_name' => __('Tipo de Perfil', 'divi'),
    );
 
    $args = array(
     'hierarchical'  => true,
     'labels'  => $labels,
     'show_ui'  => true,
     'show_admin_column'     => true,
     'query_var'  => true,
     'rewrite'  => array('slug' => 'tipo_de_perfil'),
    );
    register_taxonomy('tipo-perfil', array('perfiles'), $args);
}
add_action('init','mis_taxonomias_perfiles');

Register the metabox.

add_action( 'cmb2_init', 'perfil_cliente_register_metabox' );
/**
 * Hook in and add a demo metabox. Can only happen on the 'cmb2_init' hook.
 */
function perfil_cliente_register_metabox() {

	// Start with an underscore to hide fields from custom fields list.
	$prefix = 'perfil_cliente_';

	/**
	 * Sample metabox to demonstrate the different conditions you can set.
	 */
	$cmb_demo = new_cmb2_box( array(
		'id'            => $prefix . 'metabox',
		'title'         => 'Perfil del cliente',
		'object_types'  => array( 'clientes' ), // Post type.
	) );
    
    $cmb_demo->add_field( array(
		'name' => 'Nombre', 'cmb2',
		'desc' => 'field description (optional)', 'cmb2',
		'id'   => $prefix . 'nombre',
		'type' => 'text_small',
	) );

	$cmb_demo->add_field( array(
		'name' => 'Apellido', 'cmb2',
		'desc' => 'field description (optional)', 'cmb2',
		'id'   => $prefix . 'apellido',
		'type' => 'text_small',
	) );

	$cmb_demo->add_field( array(
		'name' => 'Fecha de nacimiento', 'cmb2',
		'desc' => 'field description (optional)', 'cmb2',
		'id'   => $prefix . 'fecha_nacimiento',
		'type' => 'text_date',
		'date_format' => 'd-m-Y',
    	'attributes' => array(
    		// CMB2 checks for datepicker override data here:
    		'data-datepicker' => json_encode( array(
    			'yearRange' => '-100:+0',
    		   'closeText' => 'Cerrar',
               'prevText' => '< Ant',
               'nextText' => 'Sig >',
               'currentText' => 'Hoy',
               'monthNames' => ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio', 'Julio', 'Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre'],
               'monthNamesShort' => ['Ene','Feb','Mar','Abr', 'May','Jun','Jul','Ago','Sep', 'Oct','Nov','Dic'],
               'dayNames' => ['Domingo', 'Lunes', 'Martes', 'Miércoles', 'Jueves', 'Viernes', 'Sábado'],
               'dayNamesShort' => ['Dom','Lun','Mar','Mié','Juv','Vie','Sáb'],
               'dayNamesMin' => ['Do','Lu','Ma','Mi','Ju','Vi','Sá'], 
               'firstDay' => 1, //Hace que la semana comience en Lunes
               //'minDate' => 0, //Hace que no se puedan seleccionar fechas pasadas
               'dateFormat' => "dd/mm/yy", //Establece el formato de fecha
    		) ),
    	),
    ) );

	$cmb_demo->add_field( array(
    	'name'             => 'Genero',
    	'desc'             => 'Elegir una opcion',
		'id'   => $prefix . 'genero',
    	'type'             => 'select',
    	'default'          => 'elegir',
    	'options'          => array(
    		'mujer'   => __( 'Mujer', 'cmb2' ),
    		'varon' => __( 'Varón', 'cmb2' ),
    		'elegir'     => __( 'Elegir', 'cmb2' ),
    	),
    ) );

	$cmb_demo->add_field( array(
		'name' => 'Celular', 'cmb2',
		'desc' => 'field description (optional)', 'cmb2',
		'id'   => $prefix . 'celular',
		'type' => 'text_small',
	) );
	
	$cmb_demo->add_field( array(
		'name' => 'Nombre contacto de emergencia', 'cmb2',
		'desc' => 'field description (optional)', 'cmb2',
		'id'   => $prefix . 'nombre_emergencia',
		'type' => 'text_small',
	) );

	$cmb_demo->add_field( array(
		'name' => 'Celular contacto de emergencia', 'cmb2',
		'desc' => 'field description (optional)', 'cmb2',
		'id'   => $prefix . 'celular_emergencia',
		'type' => 'text_small',
	) );
	
	$cmb_demo->add_field( array(
		'name'       => 'Fecha actual', 'cmb2',
		'desc'       => 'field description (optional)', 'cmb2',
		'id'         => $prefix . 'fecha_actual',
		'type'       => 'text_date',
		'date_format' => 'd-m-Y',
		'default_cb'    => 'set_to_today',
		'attributes' => array(
			'disabled' => 'disabled',
			'readonly' => 'readonly',
		),
	) );

	$cmb_demo->add_field( array(
		'name'       => 'Edad', 'cmb2',
		'desc'       => 'field description (optional)', 'cmb2',
		'id'         => $prefix . 'edad',
		'type'       => 'text_small',
		'default'    => '35',
		'attributes' => array(
			'disabled' => 'disabled',
			'readonly' => 'readonly',
		),
	) );
    
}

function set_to_today( $field_args, $field ) {
	return date( 'l' );
}

And every time a new user registers metaboxes are added to custom posts “perfiles” with their user_niceman.

add_action( 'user_register', 'agregar_cp_perfiles_usuario', 10, 1 );

function agregar_cp_perfiles_usuario( $user_id ) {
   // Get user info
    $user_info = get_userdata( $user_id );
    $user_roles = $user_info->roles;

    // New code added 
    $this_user_role = implode(', ', $user_roles );

    if ($this_user_role == 'cliente') {

        // Create a new post
        $user_post = array(
            'post_title'   => $user_info->user_nicename,
            'post_author'   => $user_info->ID,
            'post_status'  => 'publish', // <- here is to publish
            'post_type'    => 'perfiles', // <- change to your cpt
        );
        // Insert the post into the database
        $post_id = wp_insert_post( $user_post );
    }
}

Now I would need to see those metaboxes created so that each of them can modify them on the front-end.
I understand so far that I have to create a short code to call it from the front-end private area but I don’t know how to refer to the metabox created in the custom post created with user_niceman.

Thanks in advance, I appreciate your time and effort.
