@bbovenzi or @pierrejeambrun Can I get a review?

I believe this calls for an update in the FAB auth manager otherwise this menu won't be accessible.

And probably as well as a significant newsfragment to communicate that people needs to update their user permissions for them to be able to access this new 'menu'.

UI looks good. Just one nit. I feel like we should move away from show the count of rows at the top of the table.

Random question, but do you have any advice for writing better PR titles?

Think about a one sentence description in the release notes to understand what new feature was added.
