Awesome GUI VPN Configuration Management

How can I use a GUI for configuring an L2TP VPN on a system running Awesome ? I'm trying to force myself to use a tiling window manager for a period long enough to decide if I really like it better than a floating window manager. I've installed Awesome onto debian 11, that doesn't have any desktop environments installed. I've gotten through most of my obstacles, but one thing I can't seem to locate is a rich network-manager-applet. What I mean by rich, is one that has all the features required to set up a VPN with advanced configurations for L2TP IPsec and phase Algorithms. I know that, if I installed KDE or GNOME, the network manager applet in those desktops provide a GUI for setting all these advanced configurations I need to set for the network-manager-l2tp package. But, so far, on Awesome, the network-manager applets I've gotten into the tray are missing the portion of the gui for configuring advanced setting like L2TP IPsec Options, phase algorithms, and UDP encapsulation. Maybe I can install KDE onto another computer, set up the VPN, and then locate the file where this configuration is kept, and move that file to this computer as a means of setting up the VPN. Or, maybe I can figure out how to configure the VPN via the command line alone. It would probably be easier to use a GUI to generate the config files and then use that as a bases of learning how to configure VPNs without a GUI. However, maybe I can indeed get a network-manager applet into Awesome's system tray that is just a feature-rich as what's provided by GNOME and KDE. I'm open to advice and suggestions.
