Restoring Mail Icon

I inadvertently deleted the Mail icon from my iPhone 11 home screen. (I'm running 14.6.) It is not hiding in any of my folders. I can find my mail with Spotlight, but this obviously isn't convenient. When I go to the App store, I can't redownload the App because it is "open." How can I get my mail icon back with the least amount of disruption? Is there a reset that I can do that won't delete my other apps? Thank you.
