How to use the @aws-cdk/aws-autoscaling.AutoScalingGroup function in @aws-cdk/aws-autoscaling

public addCapacity(id: string, options: AddCapacityOptions): autoscaling.AutoScalingGroup {
    const autoScalingGroup = new autoscaling.AutoScalingGroup(this, id, {
      ...options,
      vpc: this.vpc,
      machineImage: options.machineImage || new EcsOptimizedAmi(),
      updateType: options.updateType || autoscaling.UpdateType.REPLACING_UPDATE,
      instanceType: options.instanceType,
    });

    this.addAutoScalingGroup(autoScalingGroup, options);

    return autoScalingGroup;
  }

public addCapacity(id: string, options: CapacityOptions): autoscaling.AutoScalingGroup {
    const asg = new autoscaling.AutoScalingGroup(this, id, {
      ...options,
      vpc: this.vpc,
      machineImage: new EksOptimizedImage({
        nodeType: nodeTypeForInstanceType(options.instanceType),
        kubernetesVersion: this.version,
      }),
      updateType: options.updateType || autoscaling.UpdateType.ROLLING_UPDATE,
      instanceType: options.instanceType,
    });

    this.addAutoScalingGroup(asg, {
      mapRole: options.mapRole,
      bootstrapOptions: options.bootstrapOptions,
      bootstrapEnabled: options.bootstrapEnabled
    });
