Access to reapply merge requests or revert changes

Content (please ensure you mask any confidential information):

I have deployed a change to a branch through a merge request.(I am a 'project owner'), however in my absence I wanted a Developer to migrate my changes from one branch to another, however they cannot see the option to do this that I normally see?

Why would this be?

I have since made this developer a 'project owner' and they can now see these options?

But in my mind I dont want to have to give all my developers this role as i dont want them to access areas such as the project admin work area?
