How to difference source application during In-App Verification

We have Wallet and Watch application on iPhone. Both of them can add card and then waiting for activation.

However, When the same card is added to Wallet and Watch respectively, waiting for the app-to-app mode to be activated. Client doesn't aware the source application. Because deeplink is exactly the same.

Any adivse how does the client have to choose which card to activate?
