Unique identifier (int) or username (str) of the source chat where the original message was sent.

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).

message_ids (``int`` | Iterable of ``int``):

An iterable of message identifiers in the chat specified in *from_chat_id* or a single message id.

message_thread_id (``int``, *optional*):

Unique identifier of a message thread to which the message belongs.

for supergroups only

disable_notification (``bool``, *optional*):

.. code-block:: python

# Forward a single message

await app.forward_messages(to_chat, from_chat, 123)

# Forward multiple messages at once

await app.forward_messages(to_chat, from_chat, [1, 2, 3])
