Adding UI?

Excuse me if this is a basic question.

What is the recommended way to add UI to, for example, the demo scene?

Should it be a Canvas - Screen Overlay, Canvas attached to Camera L or R maybe? (For WebGL, WebXR VR) Or a World Space, and if it's a world space, how to activate the 'targeting Raycast'? Not sure how to add these input triggers to the demo setup.

Thank you for your time.

There's no universal UI that would work on all cases. Better have a UI for each type of interaction - flat screens (no XR, or handheld AR), and VR or headset based AR. Regarding casting to the UI in XR mode, there's this old Samples repo https://github.com/De-Panther/WebXR-Unity-Samples that you can check. But I think that VRTK also has some handles for this, so you can look for some youtube tutorials that explains how to intergate VRTK and this package.
