On Ubuntu 22.04, I added the two lines to show the images in the menu items :

settings = Gtk.Settings.get_default()
settings.set_property("gtk-menu-images", True) # this line allows to show images of menu items

Thanks

On the other hand, the management of the "scroll-event" signal does not work.
I made the following changes and now it works :

self.status_icon.connect("scroll-event", self.scroll_event)

def create_left_menu(self):
        self.left_menu = Gtk.Menu()
        self.left_menu.connect("scroll-event", self.scroll_event)

def scroll_event(self, widget, amount):
        direction = amount.direction

Thanks
