Web App Notifications and Labels

To receive web app notifications in the browser, check the settings below.

Web App Notification Settings

To turn message sounds on or off within the app, go to Settings > Notifications.

Permission to send notifications from the web app is configured separately — in your browser's site settings (see below).

In the web app, starting with version 3.76, you can customize the notification schedule. Open notification settings, turn on Schedule, and select the days of the week and time to receive notifications.

Configuring Notifications for a Chat or Channel in the App

To enable notifications for a specific chat or channel:

  • Right-click the chat or channel and click the notifications button.
  • Or open the chat or channel properties and toggle Notifications.

Allow Notifications for the Web App in Your Browser

Badges on the Progressive Web App Icon

If the web app is installed as a progressive web app (PWA), its icon displays an unread events counter.

If you enable the small taskbar buttons mode in Windows, notification counters (badges) and numeric indicators disappear.
