EntityQueue not available as relationship for media items

I have the same problem with a media view.
There is no relation possible to EntityQueue.
Some ideas?

Can it be that simple? I wrote the following hook in my Custom-Module

use Drupal\views\ViewExecutable;
use Drupal\views\Plugin\views\query\QueryPluginBase;


/*
 * Implements hook_views_data_alter().
 */
function custommodule_views_data_alter(array &$data) {
    \Drupal::messenger()->addMessage('media_field_data');
  // Füge der media_field_data-Tabelle eine Beziehung zur Entityqueue-Subqueue-Items-Tabelle hinzu.
  $data['media_field_data']['entityqueue_sortierliste_items'] = [
    'title' => t('Entityqueue: Subqueue Items (Downloads)'),
    'help' => t('Verbindet Medien mit Subqueue Items in "sortierliste_dateien".'),
    'relationship' => [
      'title' => t('Referenzierte Subqueue Items für Downloads'),
      'help' => t('Stellt eine Beziehung zu Subqueue Items her, die Medien in "sortierliste_dateien" enthalten.'),
      'base' => 'entity_subqueue__items',
      'base field' => 'items_target_id', // Die Zielentität in der Subqueue (media.id)
      'relationship field' => 'mid',     // media_field_data.id
      'id' => 'standard',
      'label' => t('Entityqueue Items'),
    ],
  ];
}

Then I can sort the relation Sort list media and sort with this relation.
It works for me.
