How to make a telegram bot reply to messages in a channel?

Question

Python

I already know that in order for the bot to write a message to the channel, you just need to specify the channel address instead of the user id in the send_message () method. The problem is that I don't know how to make the bot track messages coming from the channel. Those. let's say I want to create a simple dice bot (simple rolling), I need the bot to read the command written in the channel and display a random number there. Can you please tell me how to implement this?
