It seems that the extension isn't actually useful in GNOME 3.36 - gnome-shell includes a log out button in the list of Power Off/Log Out options and has removed the icons completely.
I'm going to consider requesting the removal of this package from unstable in the next while unless there is any other opinions. -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Kyle Robbertze ⢿⡄⠘⠷⠚⠋⠀ Debian Developer ⠈⠳⣄⠀⠀⠀⠀ https://wiki.debian.org/KyleRobbertze
