How to Schedule a start of DMS task by AWS EventBridge via CloudFormation template?

Question

I am creting a cloudformation template. it is creating Database Migration Service Task. I need to do a scheduling of this DMS taks via EventBridge. I've created following resource in CloudFormation:-

DMSStartTaskScheduler:
      Type: AWS::Scheduler::Schedule
      Properties: 
        FlexibleTimeWindow: 
          MaximumWindowInMinutes: 300
          Mode: FLEXIBLE
        Name: DMSStartTaskRule-dev
        ScheduleExpression: cron(30 17 * * ? *)
        State: ENABLED
        Target: 
          Arn: "DMS task ARN"
          RoleArn: !GetAtt EventBridgeIAMrole.Arn

But Getting below error:-

Invalid request provided: dms is not a supported service for a target. (Service: Scheduler, Status Code: 400,

I tried to create the same Scheduler from Console, there it was working but from Cloudformation template it is giving errors. Can anyone suggest solution of it?

DMS tasks via EventBridge? Then It should be something like this.

AWSTemplateFormatVersion: 2010-09-09
Resources:
  scheduler:
    Type: 'AWS::Scheduler::Schedule'
    Properties:
      ScheduleExpressionTimezone: "Europe/Kiev"
      ScheduleExpression: cron(*/5 * * * ? *)
      FlexibleTimeWindow: 
        Mode: "OFF"
      State: ENABLED
      Target: 
        Arn: "arn:aws:scheduler:::aws-sdk:databasemigration:startReplicationTask"
        Input: >-
         {"ReplicationTaskArn":"arn:aws:dms:us-east-1:123456789012:replication-config:BGDRG5FD4LPMFOQ7SIJ2RQATROULLBB3WTJWXYY","StartReplicationTaskType":"start-replication"}
        RoleArn: "arn:aws:iam::123456789012:role/MyRoleForEventBridge"

PS: I tested and it worked.
