What happened to it exactly? What did you do?
The App Store app cannot be deleted from the iPhone, so does not need to be put back on it. It still somewhere on there.
If a search cannot find it, then check your Screen Time restrictions in Settings->Screen Time->Content & Privacy Restrictions->iTunes & App Store Purchases->Installing Apps, and make sure its turned on.
