Warning:
|

When setting :paramref:`block` to :obj:`False`, you cannot rely on adding custom

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

called when :meth:`check_update` has determined that an update should be processed by
|
|
this handler. Callback signature::
|
|
|
|
async def callback(update: Update, context: CallbackContext)

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

|
|
chat_member_types (:obj:`int`, optional): Pass one of :attr:`MY_CHAT_MEMBER`,

:attr:`CHAT_MEMBER` or :attr:`ANY_CHAT_MEMBER` to specify if this handler should handle
|
|
only updates with :attr:`telegram.Update.my_chat_member`,

|
block (:obj:`bool`, optional): Determines whether the return value of the callback should

be awaited before processing the next handler in

:meth:`telegram.ext.Application.process_update`. Defaults to :obj:`True`.
