How do I convert AWS IAM policy into casbin policy?

Question

I want to use the AWS IAM type policy and use casbin for authentication. How to convert the AWS IAM policy into a casbin policy ? Is there a sdk that can be used for conversion? The iam policy like this:

{
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "s3:GetObject",
                    "s3:PutObject"
                ],
                "Resource": "arn:aws:s3:::mybucket/*",
                "Condition": {
                    "IpAddress": {
                        "aws:SourceIp": "192.168.1.0/24"
                    }
                }
            },
            {
                "Effect": "Deny",
                "Action": [
                    "s3:*"
                ],
                "Resource": "arn:aws:s3:::mybucket/secret/*"
            }
        ]
    }
