Testing on simulator is possible following the new iOS 14 store kit testing steps here: https://developer.apple.com/documentation/xcode/setting_up_storekit_testing_in_xcode?language=objc#3625696

We should set it up in our example app so users can test with our example app easily.

This also helps us wire up automated tests on ci (XCUITests for example)!!
