I am using Ubuntu 20.04 and in my nautilus file manager, I want to add Desktop to my left panel. I tried using Ctrl + D method and it adds the Desktop on the left panel. This is basically adding Desktop as a bookmark. I can remove this Desktop by right clicking. But when I right click on already present folders in the panel(like Home or Downloads), the remove option is greyed out. How can I add Desktop to the left panel permanently and not as a bookmark.
Thanks
