I have found the endpoint from this SO question. But what is the scope need for the same.
I tried these scopes "user.read", "files.read.all", "files.read", "files.read.selected","files.readwrite","files.readwrite.all","sites.read.all", "sites.readwrite.all".
But still getting 403 error. Please find the below screenshot with Modify permission tab in graph explorer.
