Group.instance.id do or don't

I'm setting up an architecture in Azure using Azure container apps which is an abstraction on Kubernetes so your pods can scale up and down. Kafka is new for me and I'm curious about the group.instance.id setting.

I'm not sure what a heavy state consumer is in regards to Kafka but I don't think I will have one, so my question is, is there any good best practice for the setting? Should I just set it to the unique container id or is there no point or even bad practice unless you have specific use cases?

Thanks!
