So what is the send IM Chat endpoint found here? I would think that IM stands for In Meetings, meaning this is an endpoint that sends in-meetings chat messages, but I don’t think that is the case. What is it exactly? Is just Team chats? But then what is the difference between IM chats and just chats?
Also found the update live meeting chat endpoint in the API. What is that for? Why is that available and not a simple post live meeting chat?
