Send message in a chat
Namespace: microsoft.graph
Send a new chatMessage in the specified chat. This API can't create a new chat; you must use the list chats method to retrieve the ID of an existing chat before you can create a chat message.
Note: We don't recommend that you use this API for data migration. It doesn't have the throughput necessary for a typical migration.
Note: It is a violation of the terms of use to use Microsoft Teams as a log file. Only send messages that people will read.
