Orderby by term in WP_Query

You can do that using the Advanced Post Types Order https://www.nsp-code.com/premium-plugins/wordpress-plugins/advanced-post-types-order/

Thanks

Do I need to follow this tutorial for custom taxonomy order by role?
https://www.nsp-code.com/how-to-order-posts-by-category-name/

What would be the function?

function sort_by_role_name( $post_order_list, $sort_view_id, $orderBy, $query ) {
   // Change to required taxonomy
   $_apply_for_taxonomy    =   "role";
}

I tried getting all snippets of code and creating the following function:

/**
 * Sort the elements by role name, or customised catgory order
 * 
 * @param mixed $sort_list
 * @param mixed $sort_view_id
 * @param mixed $orderBy
 * @param mixed $query
 */
function sort_by_role_name($post_order_list, $sort_view_id, $orderBy, $query)
{

  //Change to required taxonomy
  $_apply_for_taxonomy    =   "role";
  if (count($post_order_list) > 1)
    return $post_order_list;
  //check if is archive or a taxonomy view 
  if (count($query->tax_query->queries) > 1)
    return $post_order_list;

  //avoid endless loop in case using this function on multiple level terms
  global $_SCN_in_the_loop;

  if ($_SCN_in_the_loop)
    return $post_order_list;

  $_is_archive    =   FALSE;
  $_is_term       =   FALSE;

  if (count($query->tax_query->queries) > 0) {
    //ensure there's a single term
    reset($query->tax_query->queries);
    $tax    =   current($query->tax_query->queries);

    if (is_array($tax['terms'])   &&  count($tax['terms'])  > 1)
      return $post_order_list;

    $_is_term   =   TRUE;
  } else
    $_is_archive    =   TRUE;

  //retrive the terms
  $args   =   array(
    'taxonomy'  =>  $_apply_for_taxonomy,
    'orderby'   => 'name',
  );

  if (count($query->tax_query->queries) > 0) {
    //ensure there's a single term
    reset($query->tax_query->queries);
    $tax    =   current($query->tax_query->queries);

    if (is_array($tax['terms'])   &&  count($tax['terms'])  > 1)
      return $post_order_list;

    $_is_term   =   TRUE;
  } else
    $_is_archive    =   TRUE;

  //retrive the terms
  $args   =   array(
    'taxonomy'  =>  $_apply_for_taxonomy,
    'orderby'   => 'name',
  );

  if ($_is_term) {
    //retrieve a list of existing terms
    reset($query->tax_query->queries);
    $tax    =   current($query->tax_query->queries);

    if (is_array($tax['terms'])) {
      reset($tax['terms']);
      $term_id    =   current($tax['terms']);
    } else
      $term_id    =   $tax['terms'];

    if ($tax['field']  ==  'slug'  ||  $tax['field']  ==  'name') {
      $term_data      =   get_term_by($tax['field'], $term_id, $_apply_for_taxonomy);
      $term_id        =   $term_data->term_id;
    }

    $args['child_of']   =   $term_id;
  }

  $terms  =   get_terms($args);

  //retrieve a list of items for each of the terms
  if (count($terms)   < 1) return $post_order_list;
  $_SCN_in_the_loop = TRUE;
  global $APTO;
  $sort_view_post = get_post($sort_view_id);
  $sort_list_settings = $APTO->functions->get_sort_settings($sort_view_post->post_parent);

  $posts_list =   array();
  foreach ($terms as  $term) {
    $args =   array(
      'post_type'         =>  $sort_list_settings['_rules']['post_type'][0],
      'posts_per_page'    =>  -1,
      'fields'            =>  'ids',
      'orderby'           =>  'menu_order',
      'order'             =>  'ASC',
      'tax_query'         => array(
        array(
          'taxonomy' =>   $_apply_for_taxonomy,
          'field'    =>   'id',
          'terms'    =>   array($term->term_id),
        ),
      ),
    );
    $term_posts_query  =  new WP_Query($args);
    $posts_list =   array_merge($posts_list, array_values($term_posts_query->posts));
  }

  $_SCN_in_the_loop = FALSE;

  return $posts_list;
}

But it doesn’t work when setting Order By to Custom Function:

My custom query is set like this and I need to order by role order:
