I'd like to understand the capabilities and limitations of OVROverlay better. We're currently investigating if its possible to render an OVROverlay (with a call, from, say, an Android library within Unity) and then interact with that overlay, much like the system UI does (a compositor layer is opened and catches interactions that are not forwarded anymore to the running app).
From the docs, I can only find hints for rendering overlays and underlays, but nothing about interacting with them.
Is that possible? If yes, are there any docs on how to achieve this effect?
