How can I enable double-click side button for Apple Wallet on iPhone?

Hi. I have a new iPhone16. Hi all. When I am double clicking the side button, Apple Wallet doesn't appear, it just locks the phone.

The option Double-Click Side Button is enable, but not editable.

However, when the wallet application is opened and i am clicking on the side button, it reacts as it should be.

Any ideas?

Thank you.
