How to disconnect from OpenConnect VPN

[David Nelson]

Hello,

First of all, thank you for your work on OpenConnect VPN.

I can successfully connect to my OpenConnect server using the 
openconnect client on Ubuntu 22.04.

But how can I disconnect? I don't see anything in the help obtained via 
openconnect --help

Googling only informed me that I could simply kill the openconnect 
client process.

Is there a more-civilized way of doing it from the command line, please?
