No Tray Menu on ZorinOS (Ubuntu 24.04 LTS)

After installing via ZorinOS Software, the tray icon appears and seems to indicate syncing status, but left and right click on the icon do nothing. Is there supposed to be an activity or settings menu of some sort?

Reproduce the missing tray-menu behavior on ZorinOS with Ubuntu 24.04 LTS, checking both left- and right-click actions on the syncing tray icon. Trace the tray integration entry point and compare the observed behavior with the expected activity or settings menu; done means the menu works as intended or the expected behavior is clearly established.
