You would be able to view the list of automations performed on a ticket, by clicking on the Activities button in the ticket page. This will display the updates made to the ticket, both manually and using automations, in a chronological order.
If you'd like to understand if the automation rules you've configured are useful for your helpdesk workflow, you can find this on the rules list page. The number of tickets that were impacted by a rule will be displayed alongside the rule.
