ECS Fargate + Service Connect Metrics in CloudWatch

We use ECS Fargate with Service Connect enabled for our microservices. I also have ContainerInsights enabled and LogConfigurations set at the task definition and ECS service levels. According to https://docs.aws.amazon.com/AmazonECS/latest/userguide/cloudwatch-metrics.html we should be able to see many different performance metrics when Service Connect is enabled. The one I need is: RequestCount.

I am able to find ActiveConnectionCount, NewConnectionCount, ProcessedBytes, and TargetProcessedBytes which are also Service Connect metrics. However, I am not able to find RequestCount in the metrics under ECS in the console.

Any ideas on how to get the Service Connect/ECS RequestCount metric to be available?
