In Classic UI both Writer, Calc have File-Wizard-Address Data Source.. where is it in Tabbed? Seems missing. I coulkd not find the ticket with an explanation. I assume it should be respectively under References, Data.
It is actually in the Writer Tabbed UI, but it is not visible: https://git.libreoffice.org/core/+/899064be931ec4bb0cd5f32f60773980470e18a2/sw/uiconfig/swriter/ui/notebookbar.ui#2138 If you look at Customize, you see it as active. It should be visible in the Tools tab. You can scroll the list all the way down in Customize and find MenuTools-AddressBookSource (.uno:AddressBookSource) It is not in Calc's notebookbar.ui at all. Not seen in 6.1 either, so seems like an old issue. Created bug 167438 for it.
