我要使用连接器
1. In my code, a login screen of azure is display but after successful login, a
blank webpage is display and I am not able to get the access token.
2. In my second try, I only use the API which return "access token" and I used
it as a data source in power bi desktop application. In desktop application, I
used the other endpoints to get data, using the access token provided by
connector and upload it on power bi service.
