To listen to a chat you don’t actually need any redirect. Since your token is for your “chatbot” for lack of a better word, you just need to get the token for your bot you’re fine. If you’re having problems with getting the events to work, I’d be happy to help.
As for calling a player avatar, you could call it when one of the events is triggered. However, I’m not sure if I understood what you’re trying to do right.
