How to use and test Wallet Transaction Shortcut in iOS Simulator?

The Shortcuts app offers the possibility to trigger shortcuts/intends when a wallet credit card is used and a new transaction is created.

I would like to add transaction details to one of my apps and use such a shortcut for it. Other apps do the exact same thing, so this should not be a problem.

Adding a shortcut to my app was not a big deal. However, how can this be tested on simulator?

When trying to add a new automatization in the Shortcuts app using a wallet transaction as trigger I cannot finish the setup dialog since the Next button is disabled. I assume this is because no card is configured.

When trying to add a card in Wallet I just receive that this was not successful.

I have connected the simulator to a Sandbox Apple ID account using a region which supports Apple Pay (US). Using a real account does not solve the problem.

Any idea how to get this working?

Using real transaction within a store could obviously not be the solution for debugging.
