Drupal 8 move something to the advanced tabs on node forms

d8_my_advanced_tab.php

<?php

/**
 * Implements hook_form_FORM_ID_alter().
 *
 * Move your field or group of fields to the node form options vertical tabs.
 */
function mymodule_form_node_form_alter(&$form, FormState $form_state, $form_id) {

  $form['mygroup'] = [
    '#type' => 'details',
    '#title' => t('My custom settings'),
    '#group' => 'advanced',
    '#attributes' => [
      'class' => ['node-form-options']
    ],
    '#attached' => [
      'library' => ['node/drupal.node'],
    ],
    '#weight' => 100,
    '#optional' => TRUE
  ];
  
  
  $form['my_filed'] = [
    // ... type, etc.
   '#group' => 'mygroup',
  ];
}

This worked perfectly. Thanks!!!
