How do I view tickets that have been escalated in a month?

Infos:

  • Used Zammad version: 5.3
  • Used Zammad installation type: source
  • Operating system: Ubuntu
  • Browser + version: chrome

Expected behavior:

For quality control, you need to be able to see how many tickets have been expired. (escalated). The problem is that if the ticket is closed, then there is no way to find out. can’t find a solution to this.

Thanks

Actual behavior:

If the ticket was escalated, but is now closed, then it cannot be found.

Steps to reproduce the behavior:
