How to block Facebook Messenger while allowing access to Facebook


I have had success in the past creating an App Definition for LinkedIn Messenger to allow access to LinkedIn while blocking the messenger functionality through and Path: /messaging/,/voyager/api/messaging/.


Has anyone had success replicating the same control to allow access to Facebook while blocking the messenger functionality?


I have also tried blocking the Post activity for the Facebook application but that only seems to work for posts on the Facebook wall and does not apply any control to Facebook Messenger.
