Return the scene three js object from the <Scene> component

[MiguelG97]

Hi there,
I was looking to embed a 3d ifc model inside the your scene.
However, I realized that the reference to the is not returning a property that can access to the three scene

  const sceneRef = useRef<SceneInterface>(null);
      <Scene
        name="Complex Scene"
        ref={sceneRef}
        sceneCenterLongitudeLatitudeHeight={
          upperArenaLongitudeLatitudeHeight
        }
      >

any suggestions on how to get the three scene?

regards
