        else
            this.emit('message-icon-added', icon);
    },  
    
  5. Add global.log("wmClass[] = " + wmClass); after the line of let role = ..., now this function should look like the following:

    _onTrayIconAdded: function(o, icon) {
        let wmClass = (icon.wm_class || 'unknown').toLowerCase();
        let role = STANDARD_TRAY_ICON_IMPLEMENTATIONS[wmClass];
        global.log("wmClass[] = " + wmClass);
        if (role)
            this.emit('status-icon-added', icon, role);
