How to track messages in a Telegram channel and then forward it?

Question

Python

There is a public channel where the bot has been added. It is required to track new messages in it, and then forward them to users from the array.

@dispatcher.message_handler()
async def on_message(message: types.Message):
    ...

A simple message handler does not respond to messages from the channel, and I also do not understand how to forward messages to aiogram. There is absolutely nothing in the documentation about message forwarding.
