Gitlab | How do I prevent from the creator of the merge request to merge

Question

I'm using gitlab and I just configured that in order to push to master, a merge request must be created BUT I don't want the merge request creator to be able to merge the request himself.

I want all the members in my team to be able to create merge request and approve merge request to other members in the team but not to themself

How can I do it?

In the repository settings (http://example.com/repo/name/-/settings/merge_requests) you can Prevent approval by author:

That does exactly what it says - a MR must be approved by not-the-author before the author can merge their own MR. As shown in the above screenshot, there are other controls that prevent trivially bypassing the approval rules.
