Reinstall the Mail app on an iPhone 15 Pro

Hello, my wife accidentally deleted my Mail app from my home screen. I have an iPhone 15 Pro running IOS 18.1.1. When searching how to add it back, all I get is to find it in the App Library (I can find it), then touch and hold the icon which should bring up an option to Add it to the Home Screen. This no longer appears when you touch and hold it. The options given are:

New Message

Search

VIP

All Inboxes

Don’t Suggest Mail

Require Face ID

Delete Mail

So now how am I to get the Mail app icon back to my Home Screen? Any help would be greatly appreciated.
