From Apple KB - Use global keyboard shortcuts on Mac,

Note: You can create keyboard shortcuts only for existing menu commands. You cannot define keyboard shortcuts for general purpose tasks such as opening an app or switching between apps.

I want to know if there is a utility or a hack to make a shortcut for a particular app work even when the app is minimized. In my case, I am trying to assign a shortcut to OBS to start/stop recording even when minimized.
