Within Teamwork Desk you can enable web notifications so that even when you are not viewing the website you can receive pop up ticket information.
To enable this click on your profile icon to the top right of Desk and select 'View Profile':
In the left pane, 'Profile' will be automatically selected, scroll down so find the option to toggle 'Send Web Notifications' on or off:
When the option to send web notifications is turned on we will send notifications to your browser as a pop up notification. These notifications use the same preferences as your agent notifications.
