How to filter to see previous Status?

[Karmandroid Singularity]

Let's say I have below statuses in the project:

1. In development
2. In Test
3. Confirmed Done
4. Reopen

The normal flow for the issue should be: In development -> In test -> Confirmed done 

But in some case when during In Test session we found an issue/bug, we will need to put status as Reopen.

So, the question is, after the task statuses changed to Confirmed Done, how do I filter which task was Reopen and which not?

status WAS "Reopen"

Here are some more examples: https://support.atlassian.com/jira-core-cloud/docs/advanced-search-reference-jql-operators/#Advancedsearching-operatorsreference-WASWAS

Thank you kind sir!

For above results how to get the assignee who marked the issue Ready for QA (a status before the reopening)

Hello,

I would like to filter status is reopened and status was reopened - how can I perform it in JQL, please?

Thank you!

status = reopened  and status was reopened
