        """Iterate through a chat sequentially.
        This convenience method does the same as repeatedly calling :meth:`~pyrogram.Client.get_messages` in a loop, thus saving
        you from the hassle of setting up boilerplate code. It is useful for getting the whole chat messages with a
        single call.
        Parameters:
            chat_id (``int`` | ``str``):
                Unique identifier (int) or username (str) of the target chat.
                For your personal cloud (Saved Messages) you can simply use "me" or "self".
                For a contact that exists in your Telegram address book you can use his phone number (str).

            limit (``int``):
                Identifier of the last message to be returned.

            offset (``int``, *optional*):
                Identifier of the first message to be returned.
                Defaults to 0.
        Returns:
            ``Generator``: A generator yielding :obj:`~pyrogram.types.Message` objects.
        Example:
            .. code-block:: python
                for message in app.iter_messages("pyrogram", 1, 15000):
                    print(message.text)
