World space UI not responding

[Christopher W. Wood]

Hello. I made a videopak with UI elements and everything worked, but it overlapped with the OP-Z app UI. I noticed the recommendation on the wiki to convert the canvas to the "World Space" render mode:

However, there are currently problems with adding screen space canvases as they conflict with the app UI. Instead, set your canvas render mode to world space.

I tried this and added my main camera as the "Event Camera", and the videopak doesn't overlap with the OP-Z app UI, but it no longer responds to touch events. I've tried changing the order in the sorting and this doesn't seem to fix the problem. Everything works as expected when I test it in Unity. Is there an option that I'm missing?
