Google maps native marker click event not firing

Ionic Native
1

I cannot get this listener to fire. Any suggestions? I feel like I have tried everything. Thanks

"cordova-plugin-googlemaps": "^2.0.11"

The marker is added to the map but the click event does not fire the alert.

        let latlng = new LatLng(spot.lat, spot.long);
        let markerOptions: MarkerOptions = {
            'position': latlng,
            'animation': 'drop'
          };


          this.map.addMarker(markerOptions).then((marker: Marker) => {
            marker.addEventListener(GoogleMapsEvent.MARKER_CLICK).subscribe(e => {
              alert('foo');
            });
          });
