Wallet

When I got my new iPhone I deleted the wallet. I need it back and when I go into the Apple apps on the App Store, it shows wallet with the option to Open so it’s somewhere on my phone. When I open from the App Store it only gives me the option to download apps I can add to my wallet (ie:Starbucks). That’s the only option. Also when I search my phone it’s not showing up. How do I restore. Thanks.
