Und in der Vorlage so

<agm-map style="height: 300px" [latitude]="51.673858" [longitude]="7.815982" [styles]="styles">
  <agm-marker-cluster imagePath="https://raw.githubusercontent.com/googlemaps/v3-utility-library/master/markerclustererplus/images/m">

    <agm-marker *ngFor="let m of markers; let i = index"
      [latitude]="m.lat"
      [longitude]="m.lng"
      [label]="m.label">
    </agm-marker><!-- multiple markers -->

  </agm-marker-cluster>
</agm-map>

aber das Kartendesign funktioniert nicht. Können Sie mir helfen, damit ich verschiedene Stilkarten von https://mapstyle.withgoogle.com/ verwenden kann?
