Adding Work App Integrations
Tandem integrates with a long list of work-related apps which allows you to share when you are working in those apps with your teammate, giving them a sense of your work mode and unlocking moments of collaboration serendipity.
Tandem doesn't integrate with all work apps, but you can easily add them to your workspace (although your teammates will need to manually toggle on any custom apps that others add.)
To add a custom app go to Settings > Work app sharing
Scroll down till you see the custom apps section and click "add a custom app"
