Can’t Delete an App Using ‘x’ on App Icon

I am trying to delete an app from my p iPhone. When I hold down any of the app icons they start to shake, but there is no "x" in the corner for any of them. I can move them around, but can't delete. I tried to remove the restrictions of removing app from my settings/general, but surprisingly I realized that I don’t have a “restrictions” section in my settings!

My device is an iPhone Xs Max with IOS 13.1.3

Can someone help?

Thanks
