在Microsoft Graph Api中使用授权类型密码设置范围

Question

我正在使用以下代码通过使用授权类型密码来获取访问令牌。我能够获得令牌，但是我在这里设置的作用域不会在重新操作中返回。在这里，我将范围设置为 Group.ReadWrite.All ，但我一直在使用范围 Calendars.ReadWrite.Shared email offline_access openid profile User.Read 进行响应。这里有什么问题，如何从这里设置范围？

 using (var client = new HttpClient())
                {
                    var content = new FormUrlEncodedContent(new[]
                    {
                new KeyValuePair<string, string>("grant_type", "password"),
                new KeyValuePair<string, string>("resource", "https://graph.microsoft.com"),
                new KeyValuePair<string, string>("username", "XXXXXXXX"),
                new KeyValuePair<string, string>("password", "XXXXXXXX"),
                new KeyValuePair<string, string>("client_id",  "XXXXXXXXXXX"),
                 new KeyValuePair<string, string>("client_secret","XXXXXXXXXXXXXXX"),
                   new KeyValuePair<string, string>("scope","Group.ReadWrite.All")

                });
                    string url = "https://login.microsoftonline.com/common/oauth2/token";
                    var result = await client.PostAsync(url, content);
                    string resultContent = await result.Content.ReadAsStringAsync();
                    return resultContent;
                }
