How can I stop Game Mode notifications on iOS?

Just updated to iOS 18.2. Now when I load a game such as chess, I get this pop-down notification telling me game mode is on - it is very annoying. I have found advice on how to turn it off, now I get a notification telling me game mode is off - to put it simply - I do not want to be told either way what is happening - I know game mode is on. I don't want to switch all notifications off
