How to hide/unhide a tab?

I’ve been using the attribute .visible to hide/unhide figures in charts but now I’ve to hide/unhide the entire tab. How can I do that? Even if I’m able to delete it, that’ll work too but hiding it is something I’d prefer to do.

AFAIK you should be able to add/remove it from the list of children that the Tab widget has (the tabs property of the Tabs widget)
