        .. note::

            If you want to create a new supergroup, use :meth:`~pyrogram.Client.create_supergroup` instead.

        Parameters:
            title (``str``):
                The group title.

            users (``int`` | ``str`` | List of ``int`` or ``str``):
                Users to create a chat with.
                You must pass at least one user using their IDs (int), usernames (str) or phone numbers (str).
                Multiple users can be invited by passing a list of IDs, usernames or phone numbers.

        Returns:
            :obj:`Chat`: On success, a chat object is returned.

        Example:
            .. code-block:: python

                app.create_group("Group Title", user_id)
        """
