You can use the below template

"DNS": {
    "Type": "AWS::Route53::RecordSet",
    "Properties": {
        "HostedZoneId": "Z058101PST6709",
        "Name": {
            "Ref": "AlternateDomainNames"
        },
        "ResourceRecords": [{ "Fn::GetAtt": ["myDistribution", "DomainName"] }],
        "TTL": "900",
        "Type": "CNAME"
    }
}

I should raise as you're using Route 53 you should take advantage of using Alias records instead of CNAME records for your CloudFront Distribution.

This could be done via the below.

{
    "Type": "AWS::Route53::RecordSetGroup",
    "Properties": {
        "HostedZoneId": "Z058101PST6709",
        "RecordSets": [{
            "Name": {
                "Ref": "AlternateDomainNames"
            },
            "Type": "A",
            "AliasTarget": {
                "HostedZoneId": "Z2FDTNDATAQYW2",
                "DNSName": { "Fn::GetAtt": ["myDistribution", "DomainName"] }
            }
        }]
    }
}
