B4J Tutorial [BANanoVuetifyAD3] Help me run gmap-cluster and get latlng in events (gmap_CenterChanged, gmap_mousemove, gmap_click)

Dear Mr @Mashiane and all,
i comeback to research BANanoVuetifyAD3 in Google Map subject
I see in VueGmap module has Sub Use:

Sub Use(vuetify As VuetifyApp)
        'ensure that the module is loaded
        If vuetify.ModuleExist("googlemap") = False Then
            Dim VueGoogleMaps As BANanoObject
            VueGoogleMaps.Initialize("GmapVue")
            Dim opt As Map = CreateMap()
            BANanoShared.PutRecursive(opt, "load.key", mGoogleMapKey)
            BANanoShared.PutRecursive(opt, "load.libraries", "places,directions,drawing")
            BANanoShared.PutRecursive(opt, "installComponents", True)
            BANanoShared.PutRecursive(opt, "autobindAllEvents", True)
            vuetify.Use1(VueGoogleMaps, opt)
'-------------------------------------------------
'        Dim Cluster As BANanoObject = VueGoogleMaps.GetField("Cluster")
'        google = VueGoogleMaps.GetField("gmapApi")
'        vuetify.ImportComponentBO("gmap-cluster", Cluster)
'------------------------------------------------------
            vuetify.AddModule("googlemap")
        End If
End Sub
