Probably an issue with the bearer token - either not provided or wrong audience. Show how you are constructing that POSt to the graph API and explain how you get the token and include it. — Josh
To send a chat Message, you should add the ChatMessage.Send permission, see here: docs.microsoft.com/en-us/graph/api/… — Diana

I tried this using graph explorer and I was able to send the message.

Note : Please make sure you have the above required permissions to send the message to the channel.
