The System event trigger executes a rule whenever a specified system event occurs.
System event configuration
Simply select one of the existing system events. The rule will be executed when that event is being picked up by the automation rule.
No further configuration is needed at this point.
It is highly recommended to further limit the execution of the rule using automation conditions (e.g. to limit execution to a single project).
