Vive system button -> OnApplicationFocus and OnApplicationPause not firing

[Jacktionman]

Hello,

We're using Vive OPENXR but when someone pushes the system button, the game runs in the background (although the Vive modal UI pops up).

Typically we use OnApplicationFocus and OnApplicationPause to deal with this functionality on other headsets. But on the Vive, it does not appear to work.

Is there some way to subscribe to this button or state change that is recommended?

@Jacktionman Could you share which headset you're using? (VIVE Pro or VIVE Cosmos)

And which active OpenXR runtime you have set?

Thanks, it's a VIVE Focus 3, the game is to run on the XR Elite.
