Meta Quest 3, Unreal 5.7: Need help with trying to get Opacity to work.

Hi, is there a way to get Opacity to work on Meta Quest 3?

The simplest and most obvious way in UE5.7 obviously refuses to work on VR glasses but I was wondering if there was some work around on this? I tried to look everywhere for any glues how to get it to work but googling around hadn't yield any results.

I'd be most grateful for any advice and help I can get.
