# Public methods on server
# All these method must first authenticate the user before it calls the private function counterpart below
# which sends the request to bbbApps. If the method is modifying the media the current user is sharing,
# you should perform the request before sending the request to bbbApps. This allows the user request to be performed
# immediately, since they do not require permission for things such as muting themsevles.
