Consumer group offset translation in Mirror Maker 2

Hi,
We're using Mirror Maker 2 for replicating messages from our primary to
secondary cluster, it's one way replication. We're also replicating by
the consumer group offsets by adding the below properties

sync.group.offsets.enabled=true
sync.group.offsets.interval.seconds=5
emit.checkpoints.interval.seconds=5

Wanted to know how the translation of consumer group happens from source to
destination cluster, especially need to know "how current offset and log
end offset translation happens from source to destination kafka cluster"

Thanks in advance.
