How to add the new unity uxml(via ui builder) to game screen?

Question

I installed the new Unity UI Builder. Everything works just fine...

But how do I add the uxml to my scene or how do I attache it to camera?

I tried to drag and drop the uxml to camera and I searched for a component, but I couldn't find anything... Is there any official documentation?

Answer 1

You must use an gameObject with PanelRenderer.cs attached to it:

For now, I only know you have to set UXML file and USS file. In play mode, by magic (I still don't understand how unity does it), it will render.

In the Github project you can see how things are for now. UIElementsUniteCPH2019RuntimeDemo

EDIT: The project linked above uses UI Builder 0.8.
