Find DeviceDetail for the currently logged in user

Hmm, interesting, none of that's in the token I have (it's actually a token acquired by a Sharepoint online webpart, but it's just a request to login.microsoftonline.com/.../oauth2/v2.0/authorize which sends back a page that redirects to https://<tenant>.sharepoint.com/_forms/spfxsinglesignon.aspx#access_token=<token>). This is all it has:
