How to close someone else's Code Review Request

Hello,

We are using the built-in Code Review tool and finding that if someone leaves a team for example, there is no obvious way to Complete or Abandon an existing Code Review Request from that user.

The reason this becomes an issue is that we are trying to create a query that shows all open Code Reviews to provide visibility for our Scrum Master/Product Owner and these old Code Review Requests add noise to the query.

Can anyone provide any suggestions?

Thanks!
