        This method will first call :meth:`~zeebgram.Client.stop` and then :meth:`~zeebgram.Client.start` in a row in
        order to restart a client using a single method.

        Parameters:
            block (``bool``, *optional*):
                Blocks the code execution until the client has been restarted. It is useful with ``block=False`` in case
                you want to restart the own client within an handler in order not to cause a deadlock.
                Defaults to True.

        Returns:
            :obj:`~zeebgram.Client`: The restarted client itself.

        Raises:
            ConnectionError: In case you try to restart a stopped Client.

        Example:
            .. code-block:: python

                from zeebgram import Client

                app = Client("my_account")

                    await app.stop()
