Work with all issues where assignee was assigned in history

Hello together.

How do I get only issues, where certain assignees have been involved (in history), but are not necessarily assigned anymore.

“A” was first assignee, and made “B” new assignee. “B” made “C” assignee who closed the issue.

I want to get/work with all issues, where “B” was involved.
(Afterwards I would like to calculate to average closing time of those issues, where “B” was involved).

Any idea? I would appreciate any help!
Thanks

We discussed the whole use case with @Ron via support email.

Usually, you can detect that the person has been an assignee if the measure “Transitions to assignee” together with this particular assignee (selected in Pages or added in a tuple with this measure) is larger than 0.
