public function handleDirectoryCreate(array &$form, FormStateInterface $form_state) {
  $form_values = $form_state->getValues();
  $directory = $form_values['directory_name'];
  // The options passed to FileSystemInterface::prepareDirectory() are a
  // bitmask, so we can specify either
  // FileSystemInterface::MODIFY_PERMISSIONS,
  // FileSystemInterface::CREATE_DIRECTORY, or both.
  // FileSystemInterface::MODIFY_PERMISSIONS will set the permissions of the
  // directory by default to 0755, or to the value of the variable
