If you require more of a break, you can always log out of Facebook Messenger. Users who are active on the Messenger app have a small green circle that appears in the bottom-right corner of their bubble. Setting your profile to inactive will reveal individuals that you are not available on the app.
At the bottom of the messages section in the app, tap the menu icon next to "House.".
Tap "Active" at the top of the menu. This will give you the option to turn chat off.
Despite the fact that you set yourself as "not active," you will still receive messages, as well as the notification pointer on the app.
If you wish to avoid notices and the option to receive messages on your mobile gadget, it's best to erase the Messenger app or turn notices off.
