I really think you’re trying to use the wrong tool for the job here. Joplin isn’t designed for your notes to be modified outside of the ecosystem, the notes themselves are markdown so you can export or transfer them, but you can’t simultaneously edit them outside of Joplin. For that you’re better off with a folder of markdown files which you can push to Git.
Joplin is essentially an open source version of Evernote and a great alternative for people who enjoyed that style of application.

With that feature the external editor is launched via Joplin, so the editing is still happening in the ecosystem. You can’t just open the notes from outside Joplin.
