iOS IAP App Store Promotion

Hi People
I recently submitted my app to the app store and uploaded an icon to the IAP App Store Promotion, where I can promote my subscription directly on the app store. They have rejected the binary because it seems it starts the app and prompts the user to buy the subscription directly without showing all of the necessary information and conditions inside of the app. According to apple I have to use this thing: SKPaymentTransactionObserver, which I have no idea what is.
Is it possible somehow to get the app store IAP promotion button to open up the proper “buy subscription” tab in my app with all the information, without having it trying to buy the subscription immediately on start up?

Thanks a lot
Rune

The SKPaymentTransactionObserver is part of Applies StoreKit. You must integrate StoreKit into your application. There’s an asset in Unity for that here (and probably others, I’m not advocating you buy it, just found it with Google). Google also showed things like this information.

The technique is beyond the scope of a post here. The point is that Apple has certain requirements, and you’ll need to search for how to integrate StoreKit into Unity applications, and pay attention that the information you find is recent enough to be applicable to a current version of StoreKit and the version of Unity you used to build your application.
