We should group the display of the code owners approvals so that it is easier to parse. > Just grouping duplicates would be a nice improvement (eg Verify backend appearing twice) > Collapsed the widget said i needed 2 approvals but when i expanded it, it’s actually the same approval required twice (Verify backend) | Current | Proposal | | ------ | ------ | | ![image](/uploads/3bed5115321d4a9f02a26c42edce4b60/image.png) | TBD | <!-- Use this section to explain the feature and how it will work.
