please add support for '-s' script field for openconnect
Description of the feature
I'd like to pass a custom script to openconnect. Mainly to use vpn-slice for split tunneling. This requires paying the script and parameters to openconnect's '-s' parameter.
I currently use this by directly invoking openconnect from the command line, but wasn't to use it via NM (GUI) instead.
Description of the use cases
Enabling split tunneling like described in
