How to know if Render Text is occluded?

I’m working on VR mini-game where occasionally Render Text parented to objects will overlap that of other objects.

I searched for an is occluded/overlapped function but couldn’t find anything. I have an idea of how to offset, but I just can’t readily find a way to know whether it’s being overlapped/obstructed to begin with.

Thanks in advance for any help in regard.
