I no longer have Remove App option available

If you are experiencing difficulties with removing Apps from your iPad, you need to check your ScreenTime restrictions:

How to delete apps on your iPhone, iPad and iPod touch – Apple Support

Try a hard reset of your iPad by holding down both the Home and sleep/wake buttons simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.

Good Luck!

Try long pressing on one of the app icons.

Turn off Screen Time, delete the app and then turn Screen Time back on.
