I seem to recall configuring it entirely (sans key generation) in KDE Plasma network settings. I'm guessing you're referring to another applet?

I'm not an expert in KDE but I mean this applet: https://gitlab.gnome.org/GNOME/network-manager-applet.git

I assume that I can't really install the KDE applet without installing the entire KDE suite, so this was my goto solution.

Edit: I see that wireguard support is in the works but is not merged yet: https://gitlab.gnome.org/GNOME/network-manager-applet/-/merg...
