[macOS 13 Ventura] Failed to register SlowQuitApps to launch on login
It seems that SMLoginItemSetEnabled() does not work in Ventura (13.0) and register() should be used instead:
To enable or disable LoginItems in macOS 13 and later, use the register() and unregister() methods instead.

... a failure is shown:

I hope someone is able to pick this up for an update.
A quick workaround: right click app icon in the dock and select Open at Login.

You guys can use my version for walk around fix. https://github.com/warkcod/SlowQuitApps/releases/tag/0.8.2 Support macOS Venture, build with Xcode v14.3, Removed the annoying popup dialog. Use crontab to fix this and also fix a bug which sometime it does not work after long time running.
- crontab -e
30 * * * * sh killAndStart.sh
Restart the app every 30 minutes slicensely.
Tested in macOS Venture V13.3.1
