    "Statement": [
        {
            "Sid": "Stmt",
            "Effect": "Allow",
            "Principal": "*",

            "Resource": "arn:aws:s3:::bucket_name/*"
        }
    ]
}

{
    "Version": "2012-10-17",
    "Id": "Policy",
    "Statement": [
        {
            "Sid": "Stmt",
            "Effect": "Allow",
            "Principal": "*",
            "Action": [
                "s3:GetBucketCORS",
                "s3:PutBucketCORS",
                "s3:GetObject"
            ],
            "Resource": [
                "arn:aws:s3:::bu",
                "arn:aws:s3:::bu/*"
            ],
            "Condition": {
                "StringLike": {
                    "aws:Referer": [
                        "https://www.com/*"
                    ]
                }
