I am trying to implement functionality where I can get list of documents from share-point.I have tried this demo code from Azure directory implementation and login to account and also got details about sites and user data from graph API.
https://github.com/Azure-Samples/ms-identity-android-kotlin
I am able to get site data from graph API :
But when I am trying to get list then getting error or no value
I have also passed this authorization token to REST API but that too doesn't work.
