MTLS Rest proxy logging

Looking for details on MTLS jetty logging for confluent Rest Proxy. Ex. Client presents cert, match, authenticated, redirect, etc. Tried enabling debug logging in log4j properties without luck

More detail-
We have ssl.client.authentication=REQUIRED enabled and auth is working with truststore that client cert is validated against.

Please confirm whether there is option in rest-proxy service startup, log4j, or somewhere else where we can enable detailed MTLS authentication requests.

Thanks Frank
