I have little to no knowledge writing JavaScript so I need a little help please.

I have created several buckets on my AWS account along with a few users. I know the correct syntax to write for denying a specific user access to a bucket but I need to deny access to two users. I do not know the correct syntax to do that :(

I have the following two users: `BarnU` and `BarnZ`

The code I have for denying access to one user is as follow:

```
{
    "Version": "2012-10-17",
    "Id": "Policy1575527937316",
    "Statement": [
        {
            "Sid": "Stmt1575527932225",
            "Effect": "Deny",
            "Principal": {
                "AWS": "arn:aws:iam::755268545265:user/BarnU"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::poloserver/*"
        }
    ]
}

```

How do I add to this script the user `BarnZ`?

Thank you
