Tap To Pay TestFlight

I'm trying to distribute our app through TestFlight's internal testing for our QA Analysts to run some tests in the non-production environment.

In this page: https://developer.apple.com/documentation/storekit/testing-in-app-purchases-with-sandbox

Is stated that: "Apps that you download from TestFlight always run in the sandbox environment." But we ran into the issue from the ProximityReaderAPI requesting a Sandbox account anyway (This token requires a sandbox test account from your Apple Developer account).

Is that not the case for Tap To Pay on iPhone?
