I like it. But I think we should either merge it with the current send_message or give it a different name, so it is more clear where the two functions differ.

And could we simplify the two functions if they are mergeable, so it could somehow autodetect if the recepient is a chat_id, a group_uid or a user?

[olizimmermann]

Ok, let me check the options here.

[olizimmermann]

Decided to merge both send_message functions. If you provide a chat_id, the continue_chat function will be called.
Also updated the update_event function. Needed to replace None with an empty String, because I saw, that some events doesn't provide all fields and a dict with a None field inside, cannot be converted to json.

[olizimmermann]

Oops. I meant a dict with a class object inside (like str) cannot be converted to json. That's why I choose None instead.

@olizimmermann or @Olen do you plan to progress this? I don't know enough about chats myself.

[olizimmermann]

What exactly do you need? Check out my latest PR #62. @elliot-100

[elliot-100]

Can you resolve the conficts in your branch? I think I can then merge it.

[elliot-100]

Thanks @olizimmermann! @Olen I've gone ahead and merged since you already reviewed the bulk of this - hope that's OK.
