Where to place Store.init in Storyboard App

Our app for iOS is using the storyboard API and it has a scene where users can purchase expansion packs for the game. This works just fine, no problem in that sense.

Anyhow, I was wondering where the store.init function should be initialized to receive the proper callbacks. Should we init it in this specific scene or globally in main.lua?
