We can get different triggers for post notifications when certain events happen in iterm2.
When a a command finishes
(even if it’s chained with other commands):
Option 1: Manually integrate the notification in the command chain
Option 2: Enable alerts
Via cmd + alt + a
or via Edit > Mark and Annoations > Alerts > Post Notifications
and this is enough to have iterm2 post a notification to the system notifications engine when the flow of control has changed to another command.

When new output is detected
For this, iterm2 has a trigger configuration, which can do a lot more than just posting notifications.
For it, go to Session > Triggers > Add Trigger...
, enter an all-accepting regular expression (.*
), and set the action to Post notification
.
