Enabling Face ID for Apple Wallet

I have just added my credit card to Apple Wallet, and I verified in my settings that Face ID is enabled for it, but whenever I close and re-open the app to test if it will prompt me to verify my Face ID, it does not. It just opens straight to my list of cards, which is concerning. I can also open the credit card without any authentication.

I am not sure if the prompt will only appear when I am about to make a purchase, but from what I can tell, the screen I see right now is the same one on the Apple Support page. Is anyone else having this security issue with using Apple Pay?
