MSGraph access to personal Teams account

[JogyX1]

Can MSGraph be used to access a personal Teams account?

When I try it in MSGraph Explorer or in code, I get this response:

{
    "error": {
        "code": "Forbidden",
        "message": "No authorization information present on the request.",
        "innerError": {
            "date": "2024-02-14T16:18:48",
            "request-id": "2d56bc50-df64-49bf-bbff-6ca46fe28a98",
            "client-request-id": "517fd4f2-6014-929a-4523-9af0cc690be5"
        }
    }
}
