deleting apps on ipad, no remove option showing

Also try long-pressing the icon and picking Remove App from the menu. If that's missing too, Settings > General > iPad Storage, tap the app and there's a Delete App button at the bottom.

Screen Time is blocking it. Settings > Screen Time > Content & Privacy Restrictions > iTunes & App Store Purchases > Deleting Apps, set it to Allow. If the iPad came from school or work it's probably managed and you won't be able to change that.
