Typically, you should do all app management through Configurations. This is the best way to install, uninstall, and generally manage your apps across all of your devices.
However, you can also view and uninstall specific apps from a device if needed. For example, you may use this to ensure a user hasn't installed or sideloaded an unapproved app on their own.
View Installed Apps
Go to your device page and click on the Installed Apps tab
Check the Show System Apps option to show every app currently installed on the device.
Uninstall an App
From the Installed Apps apps, click the ( - ) minus button on the application to remove it from the device.
