Connect IOT Core, Kafka Rule to managed Confluent Kafka cluster

I just started a test cluster on the Confluent cloud and was able to publish messages using the AWS IoT Kafka Action, here the steps I used to set it up:

• Created a VPC with two subnets
• Enabled DNS resolution on my VPC
• Attached VPC Internet Gateway and a created default routing rule on both subnets to the IGW
• Created an AWS IoT VPC Destination using both subnets created before and referenced a Security Group allowing all outbound traffic
• Attached an EIP two both ENI created by the AWS IoT Destination
• Configured the Kafka Action

aws iot get-topic-rule --rule-name KafkaConfluentTest
{
    "ruleArn": "arn:aws:iot:eu-west-1:12345678901:rule/KafkaConfluentTest",
    "rule": {
        "ruleName": "KafkaConfluentTest",
        "sql": "SELECT * FROM 'kafka' ",
        "description": "",
        "createdAt": "2022-08-04T10:24:09+02:00",
        "actions": [
            {
                "kafka": {
                    "destinationArn": "arn:aws:iot:eu-west-1:12345678901:ruledestination/vpc/8758ddb2-a2d1-4d6d-bfa2-10658b9511d1",
                    "topic": "test1",
                    "key": "",
                    "partition": "",
                    "clientProperties": {
                        "acks": "1",
                        "bootstrap.servers": "pkc-xxxxxx.eu-west-1.aws.confluent.cloud:9092",
                        "compression.type": "none",
                        "key.serializer": "org.apache.kafka.common.serialization.StringSerializer",
                        "sasl.mechanism": "PLAIN",
                        "sasl.plain.password": "${get_secret('kafka-sasl-passwor
d', 'SecretString', 'arn:aws:iam::12345678901:role/AWSIoTServiceRole')}",
                        "sasl.plain.username": "${get_secret('kafka-sasl-username', 'SecretString', 'arn:aws:iam::12345678901:role/AWSIoTServiceRole')}",
                        "security.protocol": "SASL_SSL",
                        "value.serializer": "org.apache.kafka.common.serialization.ByteBufferSerializer"
                    }
                }
            }
        ],
        "ruleDisabled": false,
        "awsIotSqlVersion": "2016-03-23"
    }
}

After publishing messages using the AWS IoT Test client to my rule, I can see a new entry in the Conflunent.cloud dashboard under Data Integration -> Clients with Client id : aws-iot-rules-engine-a1921787-6654-42aa-9a67-00f9...

If you have things you want me to test in my environment, let me know.
