How to get value from config object from index.js file?

Hey! please tell me: how to get value from config object from index.js file? Every time I try to access this variable from some scene or prefab class using game.config, I get a ReferenceError: game is not defined error. I beg you to explain how it works, how and where you can refer to config, and what is the game variable used for?

I guess you’re looking for this.game.config.

yes, thx
