Note:

If neither of :paramref:`username` and the :paramref:`chat_id` are passed, this handler

accepts *any* join request. Otherwise, this handler accepts all requests to join chats

for which the chat ID is listed in :paramref:`chat_id` or the username is listed in

Args:

callback (:term:`coroutine function`): The callback function for this handler. Will be

this handler. Callback signature::

The return value of the callback is usually ignored except for the special case of
