desktop-app-cli VS openvpn3-linux

Here is a link to the GitHub thread https://github.com/OpenVPN/openvpn3-linux/issues/171

Its open source, you can build it yourself if there is no package https://github.com/OpenVPN/openvpn3-linux

The git repository is the main source of information, and I tag all the releases with signed tags, where the tag message is the most important details for the release: https://github.com/OpenVPN/openvpn3-linux/releases/tag/v18_beta

If you don't want to add the lines to your profile, it is possible to use a different approach as well. That will require more hacking, and for script purposes I suggest using Python as OpenVPN 3 Linux ships with its own Python module (but you may use any programing/scripting language with D-Bus bindings to do the same). An example script starting a new session with possibility to provide user credentials can be found here: src/tests/python/start-tunnel2.py and to lookup the D-Bus path required for the configuration profile from a configuration name, have a look at this example: src/tests/python/configmgr-lookup-configname.py

You're on the wrong OS. The OpenVPN 3 Linux client actually gives you the ability to pre-install VPN config profiles and allow non-privileged users to start VPN sessions without having access to the content of the profile, though the config-acl feature.

On Linux you can facilitate the OpenVPN 3 Linux client, which exposes all you need via a D-Bus API directly - which should be available via node.js.

There's not much more docs than what's already in the openvpn2 and openvpn3-autoload Python scripts. Plus the various Python test scripts; in particular have a look at configimport.py and start-tunnel2.py. All of them hopefully got a reasonable amount of comments which makes sense.
