[NSFW] user api

Hello @wasef201

Sorry for the late answer. This is not UM issue, this is the WordPress restrictions.

1. Make sure you are authenticated and your users have the list_users capability.
2. By default, only users who have published posts are returned by the request. To disable this, you can remove has_published_posts from the query args, please see the hook:

add_filter('rest_user_query', 'remove_has_published_posts_from_api_user_query', 10, 2);
function remove_has_published_posts_from_api_user_query($prepared_args, $request)
{
    unset($prepared_args['has_published_posts']);

    return $prepared_args;
}

Thank you.
