How do I restore missing Home Screen icons on iPhone 11 after iOS 18.5 update?

I updated my iPhone 11 to ios 18.5 and when my phone restarted - the email icon, the safari icon, the telephone icon and (I can't remember the 4th icon that is along the bottom menu of the home screen ) are gone from the bottom bar. I have looked at how to repopulate the bar with these apps but have failed.

I restarted the phone to see if it would reset, and that did not work either.
