Hi Patrik,
* What was the outcome of this action?
With the `nm-connection-editor` you can edit it, but you can not do that
via network-manager!
That's because the settings app uses GTK 4, while `nm-connection-editor`
still uses GTK 3. In order for the strongSwan plugin to work with GTK
4, it has to be built with `--with-gkt4`. That creates an additional
version of the editor that's linked against GTK 4 (besides the one
linked against GTK 3). These are actually two shared libraries that are
loaded dynamically at runtime by the main editor plugin depending on
whether it's loaded by a GTK 3 or 4 application.
Regards,
Tobias
