  $triggeringElement = $form_state
    ->getTriggeringElement();

  // Dynamically return the dependent ajax for elements based on the

  // settings forms may be different, e.g. for layout builder, core, ...
  if (!empty($triggeringElement['#array_parents'])) {
    $subformKeys = $triggeringElement['#array_parents'];

    // Remove the triggering element itself and add the 'settings' below key.

    $subformKeys[] = 'settings';

    // Return the subform:
    return NestedArray::getValue($form, $subformKeys);
