Tray Icon for NordVPN missing

I am using NordVPN with my Zorin Pro and am missing the icon in the system tray, just to the left of the WiFi and Volume icons.

Does anybody know where I can reactivate this icon?

Welcome to the Forum!

You could look in the Settings from NordVPN if there is something to activate.
You could check if the Zorin AppIndicators Gnome Extension is active.
