This widget transmits the Netgate Device ID to Netgate's REST API, and retrieves the support information.
The connection is made using HTTPS/TLS. No other data is transmitted. If the widget
is not enabled, then no transmission is made

the file contents are displayed immediately. If not, an AJAX call is made to retrieve fresh information
