No Settings -> Window Manager in XFCE4

I am under Ubuntu 20.04, using XFCE4. When I click *Menu (Upper left cross)* -> *Settings* in the *Applications Menu* (added to the panel via this) I expected to have *Window Manager* available (PS: I needed that to setup keyboard shortcuts for window tiling , which were not set by default).
But I don't have that menu entry, this is what I have. I can go to the *Window Manager* via CLI with xfwm4-settings (source , and related old post ). By typing xfce4-+Tab (for tab completion), and likewise for xfwm4-, I realized there are quite a few other settings that do not show under *Menu (Upper left cross)* -> *Settings*. Of all tab completion alternatives (shown below), I checked executing some of them at the CLI, and then if they show in the menus. None of them were present (and perhaps none of the others as well!). These are marked with an asterisk. xfce4-about xfce4-accessibility-settings *xfce4-appearance-settings xfce4-appfinder xfce4-color-settings xfce4-display-settings xfce4-find-cursor *xfce4-keyboard-settings xfce4-mime-settings *xfce4-mouse-settings xfce4-notifyd-config xfce4-panel xfce4-popup-applicationsmenu xfce4-popup-directorymenu xfce4-popup-windowmenu xfce4-session xfce4-session-logout xfce4-settings-editor xfce4-settings-manager xfce4-session-settings xfwm4 *xfwm4-settings *xfwm4-tweaks-settings *xfwm4-workspace-settings The CLI settings available above seem a completely disjoint set compared to the menu entries. So: 1. Why are these menu entries not present? (I guess they should be automatically included) 2. How can I have them shown?
