Hello ,
I have multiple markers in my map which are shown using the code

this.map = GoogleMaps.create('map_canvas', {
      camera: {
        target: {
          lat: lat,
          lng: lng
        },
        zoom: 10,
        tilt: 30
      },
      controls: {
        myLocation: true,
        myLocationButton: true,
      }
    });
    this.map.on(GoogleMapsEvent.MAP_READY).subscribe(() => {
      alert('map ready');
      POINTS.forEach((data: any) => {
        console.log(data);
        data.disableAutoPan = true;
        const marker: Marker = this.map.addMarkerSync(data);
        marker.showInfoWindow();
      });
    });

using the code showinfowindow() only shows last marker info window.

Is it possible to shows infowindow for all the marker when loading.

Thank you
