You can use the Google Admin console to configure Connection Sever settings on enrolled Chromebook devices.
You can configure a list of Connection Server instances, a default Connection Server instance, and certain application settings.
When you configure a list of servers, the servers appear as shortcuts in Horizon Client. If you configure a default server, Horizon Client connects to that server automatically.
You configure these settings in a JSON configuration file. A Chrome administrator must use the Google Admin console to upload the JSON configuration file for the Horizon Client app. For detailed information about using the Google Admin console, see the G Suite Administrator Help.
You can install Horizon Client only on certain Chromebook models. For information, see System Requirements for Chromebooks.
