Does this demo work for Azure?

I try to use this demo on Azure, but some things wrong when I access `oauth.azure.authorize_access_token()`.
It shows that the request dosen't contain the **client_secret**
Does anyone meet the same issue? Or some demos recommended

Start at the demo's oauth.azure.authorize_access_token() call and reproduce the Azure authorization flow that reports a missing client_secret. Inspect how the demo supplies OAuth client configuration and compare the request with Azure's requirements. Done means the Azure demo completes token access without the reported missing-secret error, with the reproduction or result documented.
