Oculus Quest Screenshots

I know Oculus Quest has the ability to take screenshots via Sharing Menu but is it possible to trigger screenshots from within UE4 as well?

I’m keen to find a way to do this also. Does anyone have any ideas?

I was hoping to do it by exporting a render target to disk but there is a bug in the current version of unreal. The exported render targets are blank. Unreal Engine Issues and Bug Tracker (UE-80840)
