Cloud Formation template for AWS::ElastiCache::GlobalReplicationGroup

wanted to create Redis global datastore using CF , following the guidelines https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-elasticache-globalreplicationgroup.html

but no luck, I can create Redis cluster but not the global data store : My code:

if any one can help , I am getting This error:

globalreplication:
Type: AWS::ElastiCache::GlobalReplicationGroup
DependsOn: RedisService
Properties:
  AutomaticFailoverEnabled: false

  GlobalReplicationGroupIdSuffix: test
  Members:
    - ReplicationGroupId: !Ref ClusterName

      Role: PRIMARY

This will add the primary node and create new global data store and then need to add the secondary node in the newly created global data store , you can see the prefixes here https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Redis-Global-Datastores-CLI.html:
