Does anyone have any experience trying to get this webcam to work? I've had no luck with my typical Googling, and it's simply not detected in Cheese. It's the webcam you get if you get the 4K screen on an EliteBook 840 G5. It's the only thing not working on this laptop (though the fan cycles annoyingly from off to fast too often).

Thanks for any help with this!
