VR icon - Setting foreground and background assets in the Unity Editor?

I'm trying to understand the "Setting foreground and background assets"

I'm working in Unity and the commentary says:

"Note: If you are using Unity or Unreal, you can set these assets directly within the editors."

Where exactly is this in Unity? It doesn't appear to be under Player Settings, if anyone could screenshot or link me up to a tutorial/documentation it would be a big help.

Found it, it's in a goofy place

PlayerSettings > XR Settings > Virtual Realty SDKs

Press tiny arrow to the left side of "Daydream" and there it is
