Show a notification when VPN connection disconnects on its own - built in Windows 10 connection

I fully agree this should be standard functionality in windows. But despite 3 years wait and a new OS (W11) still no joy...

I've found a workaround which works really well. I'm using task scheduler to trigger when VPN disconnects and show a messagebox.

Please find code below. Save to a XML file. In task scheduler - press import and select XML file. Change the user account to your own.
