"unable to load VPN connection editor" on new Ubuntu/Mint/Fedora

Per "Error: unable to load VPN connection editor" for OpenConnect broken in Fedora 39 & 40 (#125) · Issues · GNOME / NetworkManager-openconnect · GitLab - it seems network manager openconnect UI plugin no longer loads on multiple Linux flavors. I tried building it myself, but my domain knowledge is seriously lacking (to the point of having to reinstall). Any help with this would be awesome. Thanks!
