How to reference game objects across scenes?

How would I set active a game object from another scene? If I’m in scene 2 and I press a button, I want that button to set a game object active in scene 1. I’m working on a game and the shop is in a different scene than the actual game, I need to know how to reference game objects across scenes or else I’ll have to start the entire project over and do it single scene. Thanks.

Put the GameObject reference in one Singleton.
