title: Detect "public status" of a Facebook app
body: <p>I've been looking at the Facebook <a href="https://developers.facebook.com/docs/graph-api/reference/v2.2/app" rel="nofollow">app endpoint</a> and it looks like you can get a lot of data about an app there. However I noticed it was not possible to detect whether the app had been made public or not. </p>
  
  <p>I have an app access token (id and secret), is there a way this can be checked for without manually logging into the app?</p>
