How can I open a new menu item to the Help menu to check for updates on Linux and get said item execute a shell command?



Per this issue I would like to implement this comment upon clicking a menu item in the Help menu entitled “Check for updates…” How do I do this? Keep in mind I don’t know Coffee or JavaScript, I just want to do this so that I can create an Atom AppImage that will auto-update.

Thanks for your time,
