        This is a convenience method that calls :meth:`~pyrogram.Client.start`, :meth:`~pyrogram.idle` and
        :meth:`~pyrogram.Client.stop` in sequence. It makes running a client less verbose, but is not suitable in case
        you want to run more than one client in a single main script, since :meth:`~pyrogram.idle` will block after
        starting the own client.

        Raises:
            ConnectionError: In case you try to run an already started client.

        Example:
            .. code-block:: python
