title: Is it possible to restrict who can complete a Pull Request in Azure DevOps?
body: <p>We are just moving from another Git-Repo-Hosting-system to Azure DevOps. In the previous system it was possible to restrict who is allowed to complete a pull request (assuming that all findings are resolved). That means the Pull request was "ready" to be merged but only specific people had the permissions to actually execute the merge.</p>
  
  <p>Looking through the documentation of Azure DevOps I have not found such a feature out-of-the-box.
  Did I simply miss it or it is not possible at all?</p>
  
  <p>Thank you</p>
