Doesn’t support custom post type

Hi I’m designing my first wordpress theme for my website and I want to use your plugin. I have a custom post type:

add_action( 'init', 'create_post_type' );
function create_post_type() {
  register_post_type( 'vmoh_user_stories',
    array(
      'labels' => array(
        'name' => __( 'Stories' ),
        'singular_name' => __( 'Story' )
      ),
      'public' => true,
      'has_archive' => true,
      'menu_position' => 5,
      'menu_icon' => 'dashicons-book-alt',
      'supports' => array('title', 'editor', 'author', 'comments', 'front-end-editor'),
      'taxonomies' => array('category')
    )
  );
}

But your plugin doesn’t work with this post type.
I have also tried this code:

add_post_type_support( 'Stories', 'front-end-editor' );

but still doesn’t work..

It works with ‘post’ s but not with ‘vmoh_user_stories’
