I'm a bit confused about Identity Providers in a project I'm doing with Xamarin Forms.

I configured Facebook as an IP with Azure Mobile Apps following this page 
<https://learn.microsoft.com/en-us/azure/app-service-mobile/app-service-mobile-how-to-configure-facebook-authentication>

It works, but my doubt is, how can I use the MobileServiceUser result of the authentication process to, for example, post to Facebook or get personal information from Facebook. Is this possible?

Thanks!
