How to broadcast game chat from game to telegram?

Question

Python

Hi, the other day I saw a channel in the telegram that broadcasts the game chat. There are also filter channels that broadcast system messages, information about bosses, messages from those users who are looking for a party, etc.
How to do it? I didn't find anything like it on the internet. I am grateful to those who will give a link to the material with which I can come to the same result.
