iOS Payment Feature Bug Fix in React Native App

I'm experiencing a consistent issue with the tap to pay features on my React Native Tap to Pay app for iOS. Stripe has given a code for their tap to pay integration. It works fine in android but when upload to test flight on apple developer console, it says tap to pay not integrated.
The app doesn't crash, and the interface responds well in Google play android version, but the tap to pay processing isn't working as it should in iOS. I'm looking for an experienced developer who can diagnose and fix this problem swiftly.
