This main client internal command switches on/off the desktop notifications for specific tabs. It must be enabled Prefs > General > Alerts first and browser requests for permission must be accepted.

This feature currently works on Chrome and Safari.

this is the initial default for all channels and PM tabs.

/notify can also be used with the /onjoin to trigger it when joining a channel.
