KiCad 7.0 "Import Non-KiCad Schematic" menu item not showing up

Hi, I have freshly installed KiCad 7.0 under Win 11 Pro and want to import an Atium schDoc file. Under File - Import I only see the menu item “Footprint Assignments” but not “Non-KiCad schematic” (see attached screenshot). Has anybody an idea about the reason of the problem?
I have meanwhile tried and found that it still works in KiCad 6.08.
Thanks,
Gervin

You have to open the schematic editor in stand alone mode, not from the ‘project manager’

Great, thanks a lot! (I didn’t expect this as it works in KiCad 6 even when I start the schematic editor from the project manager.)
