Capturing Application logs to Central log account CloudWatch using CWAgent

Can you take a look at credentials section of config file?

I am working on a configuration file to send logs to directly Cross account CloudWatch, there by to S3 to eliminate the maintanance of S3 buckets at each account level.

I am following this documentation of AWS: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Agent-common-scenarios.html#CloudWatch-Agent-send-to-different-AWS-account

Normally without credentials section, logs were going to same account CloudWatch. But if I add credentials section and add related policies in the sender and receiver account, I couldn't see logs in receiver's CloudWatch.

Config File:

{
  "agent": {
    "credentials": {
      "role_arn": "arn:aws:iam::512425977391:role/CWAgent-Receive-Role"
    },
    "metrics_collection_interval": 60,
    "region": "us-east-1",
    "debug": false
  },
  "logs": {
    "logs_collected": {
      "files": {
        "collect_list": [
          {
            "file_path": "C:\\AppData\\*",
            "log_group_name": "Server-1",
            "log_stream_name": "{instance_id}",
            "retention_in_days": 7
          }
        ]
      }
    }
  }
}

IAM Policy at Sender Account is: Role Name: CWAgent-Send-Role

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "sts:AssumeRole"
            ],
            "Resource": [
                "arn:aws:iam::512425977391:role/CWAgent-Receive-Role"
            ]
        }
    ]
}

IAM Policy at Receiver Account is:(Which is added to trust relationship)

Role Name: CWAgent-Receive-Role

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::166355562301:role/CWAgent-Send-Role"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}
