I want to be able to create up to 16 workspaces on multitask view.  I already tried setting up both com.deepin.wrap.gnome.desktop.wm.preferences.num-workspaces and org.gnome.desktop.wm.preferences.num-workspaces to 16 on dconf editor and then restarting my computer, but I'm still limited to 4 workspaces. How can I change this?
