Oauth2.0 Access token user identifier

Hi guys,

We've implemented the Oauth2.0 authorization workflow using latest version (2020.202.0) of MYOB AccountRight API for C#.

We need to know MYOB user identifier who has been authorized. Due to MYOB documentation we can obtain it while exchange code for access token as example JSON looks like: 

{
    "access_token": "xxx",
    "token_type": "bearer",
    "expires_in": "1200",
    "refresh_token": "",
    "scope": "CompanyFile",
    "user": {
        "uid": "28_[TRUNCATED_FOR_READABILITY]_5c",
        "username": ""
    }
}

So we make call to API this way:

var handler = new OAuthRequestHandler(MyobSettings.DefaultApiConfiguration);
var request = WebRequest.CreateHttp(MyobSettings.Default.Endpoints.AccessTokenUrl);
var response = await handler.GetOAuthTokensAsync(request, "code");

HttpStatusCode status = response.Item1;
OAuthTokens token = response.Item2;

The problem is OAuthTokens class doesn't contain property "User". How can we get the currently authorized user identifier ? Probably use some other method that will get the user info ?

Thanks in advance,

Evgeny.
