Hi,
after searching the Web unsuccessfully for many hours, I decided to give the Unity Forums a try with this Problem: I’d like to Pause my Game, whenever the User invokes the Oculus Menu (Dash or Home) by pressing the Oculus Home button on the Controller (I’m working with an Oculus Rift CV1 btw)
So far I’ve only managed to register when the Unity Application loses Focus by using OnApplicationFocus. Unfortunately this doesn’t work for the Oculus Menus.
From what I could read elsewhere, it seems like querying OVRManager.hasInputFocus was a simple way to find this out. But I’m not sure how or if the whole OVRManager stuff is still accessible when using the new XR Plugin Management stuff.
I’m kinda lost … so any sort of help would be very much appreciated! 
Regards,
Onur Pekdemir
