How to use the old render feature (ARBackgroundRendererFeature) for ARFoundation - URP, with the new RenderObject (Experimental) in URPAsset_renderer ?

There is not way to create the older render feature. How does the render object work ? What are the necessary changes to make it in the Rendering Pipeline Asset work with AR Foundation ?

ARFoundation 3.0.+ has a default ARBackgroundRendererFeature in the list of custom render features that could be added. I figured this out and putting it up here just in case someone else faces this issue.
