Or maybe automate it as part of the group approver assignment? And have some feedback that you made the link? - This issue _does not_ apply to the parent group of the project. That is handled in #1593. - This issue _does not_ apply to individuals that appear in the search box. Those are handled in https://gitlab.com/gitlab-org/gitlab-ee/issues/1593. Those restrictions are handled in #1593. - This applies to both the project settings and the per merge request settings. ### Design ##### Has no results Copy: `No matches found. [Share this project with a group] or [add a user as a member] to include them as an approver.`  ##### Has some results-01 Copy: `Can't find a group or user? [Share this project with a group] or [add a user as a member] to include them as an approver.`  ##### Has some results-02  ##### Send user back to the previous page  - The message bar is fixed on the top when scrolling down.  <!-- triage-serverless v3 PLEASE DO NOT REMOVE THIS SECTION --> *This page may contain information related to upcoming products, features and functionality.
