How to add shortcode for “My Bookings”?

Dear all,

I’m trying to add the template “my bookings” to a Ultimate Member’s custom account tab.

Found following code snippet here in this support fourm which is over 2 years old:

function em_shortcode_my_bookings() {
	ob_start();
	echo '<h2>' . esc_html__('My Bookings', 'events-manager') . '</h2>';
	em_locate_template( 'templates/my-bookings.php', true );
	$output = ob_get_clean();
	return $output;
}
add_shortcode('my_bookings', 'em_shortcode_my_bookings');

My problem: It doesn’t work (anymore?). The template has not been added.

What did I wrong? Here the complete code I’m using:

/* add new tab called "veranstaltung" */

add_filter('um_account_page_default_tabs_hook', 'my_custom_tab_in_um3', 100 );
function my_custom_tab_in_um3( $tabs ) {
	$tabs[400]['veranstaltung']['icon'] = 'um-icon-calendar';
	$tabs[400]['veranstaltung']['title'] = 'Veranstaltungen';
	$tabs[400]['veranstaltung']['custom'] = true;
	$tabs[400]['veranstaltung']['show_button'] = false;
	return $tabs;
}
	
/* make our new tab hookable */

add_action('um_account_tab__veranstaltung', 'um_account_tab__mytab2');
function um_account_tab__mytab2( $info ) {
	global $ultimatemember;
	extract( $info );

	$output = $ultimatemember->account->get_tab_output('veranstaltung');
	if ( $output ) { echo $output; }
}

/* Finally we add some content in the tab */

add_filter('um_account_content_hook_veranstaltung', 'um_account_content_hook_mytab2');
function um_account_content_hook_mytab2( $output ){
	ob_start();
	?>

<div class="um-field-area">

<div class="um-field um-field-newsletter um-field-select um-field-type_select" data-key="lilalaune">
<span style="font-size: 16px!important;">Hier kannst Du alle Veranstaltungen sehen, für die Du Dich angemeldet bzw. Tickets gebucht hast.</span>
</div>
	
	<?php

function em_my_bookings_shortcode( $args = array() ){
	ob_start();
	em_locate_template('templates/my-bookings.php',true, array('args'=>$args));
	return ob_get_clean();
}
add_shortcode ( 'my_bookings', 'em_my_bookings_shortcode');
		?>

	
	

</div>

	
	<?php

   $output .= ob_get_contents();
   ob_end_clean();
   return $output;	
	
}

Thanks for your help in advance.
