i don't think it's possible to listen to DistributedNotificationCenter events with the launch plist 😭

ohai DBS 😅

Nah I haven't found a way to do it based on events via launchd. I just run this utility in the background all the time. But it's pretty tiny, and works a treat.

Now I just need to find a way to get it to work with Kitty.
