I made a simple pop-up that’s webXR-friendly for someone, and thought this might be something we’d want to include in the core repo.
Notification dialog | Babylon.js Playground (babylonjs.com)
It’s basically a custom HolographicSlate right now, but do people think it’d be good to have as a premade Control?
Related, I found this forum post before, which sounds like they wanted the same thing:
Manage on click event and open popup in WebXr - Questions - Babylon.js (babylonjs.com)
this is awesome! Can probably be in our documentation demo? Or do you see that as a dialog component?
I was imagining adding it as a dialog component, so developers can specify the title, body, and buttons, then trigger the pop-up to appear in front of the user.
I’m fine with including it in a demo though, since it showcases one way to make a clean-looking dialog for XR/3D experiences.
If it makes sense to add all of the plumbing in a single component, let’s do that! Will probably have to wait for after 5.0 release though
If it’s going into core it might be worth setting the button’s hoverCursor to pointer. 
In XR, the “hover cursor” is a little round dot from the ray from the controller. If something is not pickable, then no dot (at least in Oculus. I do not have one of enterprise AR headsets).
Now if you are also indicating that a dialog box exist in 3D space, regardless of being in XR or not, then that might be a different story.
