        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 single client less verbose.

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

        Example:
            .. code-block:: python

                from pyrogram import Client

                app = Client("my_account")
