Just to confirm so I don't break anything accidentally, I currently have the app version where Bambu Studio is how I send prints to my Bambu P1S and I can look through its camera and see what filament is where and so on, but I also have the token that Home Assistant uses to watch the printer and its camera etc.

This isn't the thing you're talking about. There's a mode where I can send prints directly over the network which disables Bambu Studio, I assume?
