navigations 'expand sidebar' width javascipt offers no administration access.

Not sure what this issue is for: to add a logo when the Navigation is collapsed on mobile or to make it work on mobile without JS? If it's the first, the designs have already explored the logo on mobile and discarded it. The reason is that it will need to hold more elements beyond the existing toggle. If it's to get this working without JS, 🐛 The toolbar should be usable without JS Needs work . Let's clarify what this is for and make sure that issues focus on solving 1 problem only. :)

“Expand toolbar” is too generic, and not clearly linked to the new Navigation toolbar. It would be best to write “Display admin menu”. That way, no need to add a logo.

I prefer “Display admin menu”, but “Expand admin menu” also work.
