Gnome Desktop item in sidebar van Nautilus

https://askubuntu.com/questions/1080582/how-to-bring-back-my-desktop-icon-in-nautilus

The Desktop icon showed up finally, when I set the dconf path /org/gnome/desktop/background/show-desktop-icons to true (I disabled it with intention before).

This setting controls whether on the Desktop shows the files in the Desktop folder. But I seems also to control the appearance of the Desktop icon in the spaces side bar for whatever reason.

I wouldn't call it a proper answer to my question, but I think that's the best I can do at the moment.

gsettings set org.gnome.desktop.background show-desktop-icons true
