A sad story: :disappointed:
It is my first extension. I spent a day watching videos and reading documentation to make this extension, and then I found how to open an external shell from an editor with the correct directory - Ctrl + Shift + C. :man_facepalming: So, you probably do not need this extension. But if you want just copy your app's path, you are welcome :smiley:
Copy workspace path.
In other words, the path of your project's root folder.
Open Command Palette and type copy-workspace-path to copy or press Ctrl + Alt + P ( to change it you can find the command copy-workspace-path in keyboard shortcuts )
