Storekit product not loading in TestFlight testing

Hello everyone, I achieved my MacOs app and distributed for "App Store Connect" and I already have setup the Product In App Purchase in the App Store connect, and I even tested the purchase flow using the local .storekit file using the "Edit Schema". And now, when I remove the edit scema's storekit file and archieved the app and used the Internal testing and installed the app using Testflight, I see that the product is not showing, an empty product array is being returned and there is no option to purchase.

I don't want to sumit the full app until I test the StoreKit integration in real test
