Question: Is there a way to get the status of all consumers inside a consumer group?

Hi team, thanks for all your efforts with this library.

I'm opening a ticket because I couldn't find any relevant information in the documentation—if it's there, I apologize for the oversight 😅.

Essentially, I want to reset the offsets of a topic by a specific timestamp. The documentation mentions fetchTopicOffsetsByTimestamp and setOffsets. However, it has the following warning: "The consumer group must have no running instances when performing the reset". We can easily stop the consumer on our current instance, but is there a way to stop the rest of consumer instances in the consumer group? I was considering sending a disconnection event to a global topic, which would prompt all instances receiving this message to check for any active consumers within the same group. If others are active, just stop the current consumer; if none are active, it would stop and reset the offsets with the methods mentioned above. However, I can't find a way to get the information related to the consumers in a consumer group. Am I missing something, or is this functionality currently not supported?

You can use the describeGroups Admin function to list the group members with their IPs and currently subscriptions.
