New Publish mode UI missing Animation and breakpoint?

I haven’t used the new Publish UI until now but notice it’s missing key features of the legacy UI. Namely the “Animate” tab and the tablet breakpoints along with the ability to switch between breakpoints. Is it hidden somewhere in that UI? I can’t seem to find any reference to it in the docs as they seem to be all focused on the classic UI.

Any help would be appreciated. Starting to worry that the evolution of vibe coding is effecting the experience in ways that seem strange.
