How to add buyable players?

Hello, so I am trying to find out how to make a scene that is accessible from the menu (I have already added the scene) and I am trying to make players able to buy characters in the game. (ie: You purchase a player from a store in subway surfers, temple run, ect) but don’t know the code to change the player in my levels, I also don’t know how to add in-app purchases (To get the character)
Any suggestions?

All references to the player in your scene, and how you handle the player’s instantiation, should be reference something that contains the prefab that needs to be used depending on their purchase instead of statically “hard coding” the player into the scene.
