Unable to access tabs in edit mode

I’m building a site that stores a lot of content behind tabs. Looking to handover the site to my client, they need to be able to edit the content inside of a tab in the Webflow edit mode.
When i try now i can only change the label text of the tab, when i click the parent AKA the tab link nothing happens (note that the label is smaller than the container so that is not the problem) .

Is this just a very obvious feature that is not possible in the Webflow editor or am i missing something here?

I think this is not possible inside of Webflow editor, someone correct me if Im wrong.

You need to change it yourself in design mode by choosing each tabs manually
