Best way making a 3D interactable level select scene like Overcooked?

Hey fellow developers!

I'm currently doing a personal project where the game is split up into several levels where getting one star should unlock the next level, etc.. Instead of doing a simple level manager UI, I want to make one where you access a level by moving the player to the level trigger (like in Tool's Up or Overcooked). What would be the smartest way of setting this up? Any projects that I can access/buy for looking into how other people have done this? Can't find anything on the Asset Store.

I'd imagine setting up the individual levels with scriptable objects.

Thanks!
