wp_insert_post没有在WP Admin面板中显示

Question

so i want to add post programatically with my plugin, i write this code:

    $my_post = array(
    'post_title'    => 'My post',
    'post_content'  => 'This is my post.',
    'post_status'   => 'draft',
    'post_author'   => get_current_user_id(),
    'post_category' => array(1)
  );

  // Insert the post into the database
  $post_id = wp_insert_post( $my_post );

and this is return post ID to variable but post doesnt show in wp admin posts table. WordPress is counting this like new post but doesnt show. Why?
