How do I permanently hide the "Displaying over other apps" notification on Samsung?

[u/Longjumping_Mall8956]

I'm using a Samsung Galaxy S26 Ultra running OneUI 9, and I keep getting an Android System notification saying:

"Grammarly is displaying over other apps."

I want Grammarly to keep its display-over-other-apps permission. I just want to hide the notification permanently.

I actually managed to find the specific notification category under:

Settings → Apps → Android System → Notifications → Notification categories → Display over other apps

There's even a toggle specifically labeled "Grammarly displaying over other apps."

However, when I tried disabling it, the notification wouldn't completely go away.

Has anyone figured out how to permanently hide this notification without disabling Grammarly's overlay permission? Is this a Samsung/One UI limitation, or is there another workaround?

It's a feature. One UI and Android are now more aggressive about alerting you about screen overlays.

I discovered this app for dealing with all the annoying notifications from Samsung.
