Exclude sky and floor from AR-immersive WebGL export

Hi,

Found out that "immersive-ar" does work. Now my next question is how to exclude sky and floor from AR-export? Now WebGL project overlays All objects in project like it should but it also overlays sky and floor over the "real"-view from phone camera so I cannot see real environment at all just environment similar to godot editor view. Below are pics of what is wanted and what I get. Wanted pic is from Unity WebGL project.
