You can also turn on Do Not Disturb to disable all push notifications. The Do Not Disturb setting allows you to mute all push notifications. You can schedule your downtime by turning on Schedule Do Not Disturb. You can also add contacts to your VIP List, meaning you will still receive push notifications when they contact you, even if you’ve turned on Do Not Disturb.
Get someone’s attention by tagging them with an @mention. To tag someone, type @ before the person’s name. Matching names will display as you type. Select the name you want to tag from the list and the name will turn blue (Figure 2 ):

When you send your message, the person you @mentioned will receive an alert in their bottom nav under Notifications. Likewise, if someone @mentions you, it will appear in your Notifications.
