Issue with Teams 'Add a User to Group Chat' API call?
I am getting a very strange error when trying to add a new user to an existing group chat using a GraphQL call. I have looked through the documentation, asked AI, and even contacted Microsoft support...

Sayali, your response is incorrect. I am following the exact API call format specified by the documentation.
https://graph.microsoft.com/v1.0/chats/IDHERE/members
{
"chatType": "group",
"\u0040odata.type": "#microsoft.graph.aadUserConversationMember",
"user\u0040odata.bind": "https://graph.microsoft.com/v1.0/users/IDHERE",
"roles": []
}
