Is it possible to assign anyone to review a pull request?

Hi, I am using Github Enterprise.
Let’s say if there is an organization and a repository under it,
is it possible to assign a person to review a PR who is not in the organization?

Hello @johnny94 :wave:

Organization members can assign a pull request review to any person or team with read access to a repository. You can add an outside collaborator with read permission to review your PRs for your org.
