If you have an iOS 10 or later device, you can add the Horizon Client widget to the iOS device's Search screen.
To add the Horizon Client widget to the Search screen, click Edit on the Search screen, tap the green plus (+) button next to Horizon Client in the widget list, and click Done.
If you have never connected to a remote desktop or application, the Horizon Client widget displays No desktop/application was launched yet. After you connect to a remote desktop or application, a shortcut for the recently used remote desktop or application appears in the widget. You can tap this shortcut to open the remote desktop or application from the Search screen.
If you have a 3D Touch-enabled device, the Horizon Client widget can appear in the quick action menu when you apply pressure to the Horizon app on the iOS device's Home screen.
