How to catch logs of external endpoint getting triggerred in cloudwatch aws

Question

Im new to aws and was trying to use Event brigde and api destination for pinging and endpoint. I am successful in creating api destination and api connection using cloud formation template and also successfully created IAM role and rule for the same, but i want to have the logs in cloudwatch triggering that endpoint after a scheduled expression. (There is no event triggering that endpoint, i want to trigger it after every 5 min)

Below is my cloud formation template

    Type: AWS::IAM::Role
    Properties:
      AssumeRolePolicyDocument:
        Version: '2012-10-17'
        Statement:
          - Effect: Allow
            Principal:
              Service:
                - events.amazonaws.com
            Action:
              - sts:AssumeRole
      Path: '/jobs-role/'
      Policies:
        - PolicyName: eventbridge-api-destinations
          PolicyDocument:
            Version: '2012-10-17'
            Statement:
              - Effect: Allow
                Action:
                  - events:InvokeApiDestination
                Resource: !GetAtt Destination.Arn

  ApiConnection:
    Type: AWS::Events::Connection
    Properties:
      AuthorizationType: API_KEY
      Description: Connection to API
      AuthParameters:
        ApiKeyAuthParameters:
          ApiKeyName: authorization
          ApiKeyValue: MyAPIkey
  Destination:
    Type: AWS::Events::ApiDestination
    Properties:
      ConnectionArn: !GetAtt ApiConnection.Arn
      Description: API Destination to send events
      HttpMethod: POST
      InvocationEndpoint: !Ref ApiDestinationInvocationEndpoint
      InvocationRateLimitPerSecond: 10

  RecordsRule:
    Type: AWS::Events::Rule
    Properties:
      Description: !Sub 'Trigger ${RecordsRole} according to the specified schedule'
      State: ENABLED
      ScheduleExpression: "rate(5 minutes)"
      Targets:
        - Id: !Sub '${RecordsRole}'
          Arn: !GetAtt Destination.Arn
          RoleArn: !GetAtt RecordsRole.Arn
          HttpParameters:
            HeaderParameters:
              Content-type: application/json;charset=utf-8
