Kafka Mirror maker 2.0 and Kafka connect REST API

I am using Kafka mirror maker 2.0 in distributed mode with 2 instances part of the same replication herd.
I am starting the service like this
./bin/connect-mirror-maker.sh config/connect-mirror-maker.properties

I am aware that MM2 uses Kafka Connect under the hood and Kafka connect comes with a REST API for querying and managing the connect workers : Monitoring Kafka Connect and Connectors | Confluent Documentation

But when I start MM2, I don’t see the REST interface being available at port 8083
I even tried adding the following configurations to explicitly start the connect REST interface but that didn’t seem to work either.

rest.port=8083
rest.advertised.port=8083

How can I get this working ?

Also, the primary reason for doing this is that I need to reset offsets for some topics which are being mirrored.
There is no way to do that right now. There is an open KIP but no activity there : https://issues.apache.org/jira/browse/KAFKA-4107
