Receive messages from Messenger group chat using Python

Question

I'm trying to implement a bot chat in a facebook account (Not in a facebook fanpage). I don't know how to check if someone send me a message so I can response. There are a Python lib used to support this feature called fbchat but it's not supported this feature anymore. Is there anyway i can resolve this problem ? I tried using selenium to login and find exact a specific conversation automatically, but i still haven't figured out how to solve the problem yet. Thank you for reading
