How to stop ads opening the app store

How to stop ads opening the app store? Nearly every in-game advertisment in games my kid is playing is presenting an App Store window with the game to be installed. Of course I have Passwort protected this. But this is so annoying! Why apple is not preventing this?

The issue is 10 years old Pop ups "force open" App Store - Apple Community

It can't be that hard to implement an 'block other apps to trigger app installations', right?
