How to make ViewportFrame objects appear behind Workspace objects

By default, objects inside ViewportFrames appear in front of objects in the Workspace. How can I make them appear behind objects in the Workspace while keeping the ViewportFrame fullscreen?

Here are some Forum posts that can possibly help you with your task at hand.

Thanks for your help, but sadly, none of these have worked. I saw someone saying BillboardGuis might work, which I have thought about too, but I don’t know how I could keep a BillboardGui fullscreen all the time. I looked it up, found nothing. Could you maybe help me with that?

I have no clue sadly how to make a billboard frame fullscreen.

That’s okay, thanks for replying!
