How to stop "Messenger is displaying over other apps" notification on Android 7.0

[Android Central Question]

Recently I keep getting this notification pop up. If I click it it just prompts me to switch off the permission but I want the chat heads that are used on Messenger.

I've found ways to switch it off on Android Oreo but nothing for Nougat. Please help.

I have a Samsung Galaxy S6.

I have an S7 Edge and it's been happening after some sort of software update, never had it before and it's annoying the hell out of me because I have notification reminder on.
