How to deploy java 17 lambda function through cloud formation

I'm planning to deploy java 17 function to AWS lambda. But since as per the documentation AWS didn't provide a bas image for java 17.

https://docs.aws.amazon.com/lambda/latest/dg/lambda-java.html

So I have a problem with what value should I use in cloudformation template Runtime field

"AMIIDLookup": {
    "Type": "AWS::Lambda::Function",
    "Properties": {
        "Handler": "index.handler",
        "Role": {
            "Fn::GetAtt": [
                "LambdaExecutionRole",
                "Arn"
            ]
        },
        "Code": {
            "S3Bucket": "lambda-functions",
            "S3Key": "amilookup.zip"
        },
        "Runtime": "Java11",  # what is the alternative for this
        "Timeout": 25,
        "TracingConfig": {
            "Mode": "Active"
        }
    }
}
