I'll just leave my quick and ugly temporary solution here on how to send messages to the different topics with the current state of this package, just in case someone might find it helpful: https://go.dev/play/p/7w6uMC6XB3P

It appears adding this functionality to the package would be as easy as adding ThreadID int to the BaseChat and BaseEdit structs in configs.go file and adding something like
params.AddNonZero("message_thread_id", chat.ThreadID) to the BaseChat implementation of params() method
&
params.AddNonZero("message_thread_id", edit.ThreadID) to the BaseEdit implementation of params() method

But surely it's more than that and we'll just have to wait for someone with some spare time to go over this.
