How to enable real time metrics on production cloudfront distributions via cloudformation

Question

So I see the documentation for this here.
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-monitoringsubscription-monitoringsubscription.html

But how does that actually work in practice?  I can't find an example of this any where.  Where would "RealtimeMetricsSubscriptionConfig: RealtimeMetricsSubscriptionConfig" go in this cloudformation template?

```
Resources:
  AssetsDomainCDN:
    Type: AWS::CloudFront::Distribution
    DeletionPolicy: Retain
    Properties:
      DistributionConfig:
        PriceClass: PriceClass_100
        Origins:
          - DomainName: "bar.foo.com"
            Id: "bar.foo.com"
            CustomOriginConfig:
              HTTPPort: 80
              HTTPSPort: 443
              OriginProtocolPolicy: match-viewer
              OriginSSLProtocols:
                - TLSv1.1
        Enabled: true
        HttpVersion: http2
        DefaultCacheBehavior:
          AllowedMethods: [GET, HEAD]
          TargetOriginId: bar.foo.com
          Compress: true
          ViewerProtocolPolicy: allow-all
          ForwardedValues:
            Cookies:
              Forward: none
            Headers: []
            QueryString: false
```

Hello.

I think it will work if you set the template as follows.  
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-cloudfront-monitoringsubscription.html  
```
Resources:
  AssetsDomainCDN:
    Type: AWS::CloudFront::Distribution
    DeletionPolicy: Retain
    Properties:
      DistributionConfig:
        PriceClass: PriceClass_100
        Origins:
          - DomainName: "bar.foo.com"
            Id: "bar.foo.com"
            CustomOriginConfig:
              HTTPPort: 80
              HTTPSPort: 443
              OriginProtocolPolicy: match-viewer
              OriginSSLProtocols:
                - TLSv1.1
        Enabled: true
        HttpVersion: http2
        DefaultCacheBehavior:
          AllowedMethods: [GET, HEAD]
          TargetOriginId: bar.foo.com
          Compress: true
          ViewerProtocolPolicy: allow-all
          ForwardedValues:
            Cookies:
              Forward: none
            Headers: []
            QueryString: false

MonitoringSubscription:
    Type: AWS::CloudFront::MonitoringSubscription
    Properties: 
      DistributionId: !Ref AssetsDomainCDN
      MonitoringSubscription:
        RealtimeMetricsSubscriptionConfig:
          RealtimeMetricsSubscriptionStatus: Enabled
```
