The following functionality is currently provided by the Admin Toolbar → Extra Tools sub-module.
Expected result: there is a local task menu, with the following sub-items:
Presumably with Navigation also installed, or else completely replacing or obsoleting Admin Toolbar, the local task menu would be incorporated into the left side bar navigation.
If Admin Tool Bar isn't compatible with Navigation, then I would expect there to be some other means by which I could incorporate such a menu and sub-menu into the navigation menu.
I ran across the issue 🐛 Media and Blocks Admin routes show local tasks as a dropdown top bar instead of tabs Fixed , which may or may not be related or may already cover the above task. However, there were no screen prints attached and I was unable to determine from the code whether this was related.
As a sidenote, I dislike the "local task" label as being jargon unfriendly to website editors, and have separately filed 🐛 "Local tasks" is hard to understand Active .

Navigation does have a 'top bar' plan!
This is a quick list of the [Plan] items in progress.
