how to config kafka consume group for kafka connector

[njalan]

In my case each topic need to apply the consume group access,So how to config the consume group ?
I got below error message and I think it is due to consume group missing.

Trino Kafka connector doesn't use consumer groups since each worker needs to read pre-determined portion of the topic.

Why do you want to use consumer groups?
The error message has nothing to do with consumer groups. It's also just a warning and it's fine for KafkaClient to disconnect since it can and will reconnect to a different broker over time.
