World Space Canvas camera reference from another loaded scene? (runtime)

I can’t seem to select the camera from another scene while multiple scenes are loaded. Likewise, this element isn’t getting any input events as I cannot select the camera from the loaded scene.

If this isn’t possible, it prevents the capability of having any UI elements in DontDestroyOnLoad since you can’t reference the camera in the active scene.

Were you able to resolve your issue? I think I’m having a similar issue. When I add my UI scene additively, I cannot interact with it. I can see that when I attempt to click on the UI, I am getting the world space location of the mouse in the Game scene, not the UI scene.
