3d widget tracing?

How can you use linetraces with 3d widgets ? i only get the actor, not any widget components, let alone the button elements on it…

It would be great to have a hitresult for 3d widget that gives access to all elements inside it, so you can fire rollover and click events with your gaze in VR for example…

Any workarounds, or do i have to build my own menu BP’s with textrender components ?
