Docker images license

We are using Kafka on Azure Event Hubs and need to use Kafka Connect as a source to watch on MongoDB changes streams and send those changes to a topic. My question is about licensing. Following this tutorial from MongoDB, it uses the image confluentinc/cp-kafka-connect-base. Is an Enterprise license required to use this on our cluster? According to this reference, I understand that a Confluent Enterprise License is necessary, but I’m a bit confused about it.

You can use Debezium images which are Apache 2.0 license

Thank you! I’ll verify
