I want to write Connect Rest request/response into custom log file.

I have updated the prlog4j2.xml with following :

1. Added Appender:

<RollingRandomAccessFile  name="RESTCONNECTORLOGS" fileName="${sys:pega.logdir}/RestConnector.log" filePattern="${sys:pega.logdir}/RestConnector-%d{MM-dd-yyyy}-%i.log.gz">
   <PatternLayout>
      <Pattern>%d [%20.20t] [%20.20X{tenantid}] [%20.20X{app}] (%30.30c{3}) %-5p %X{stack} %X{userid} - %m%n</Pattern>
   </PatternLayout>
   <Policies>
      <TimeBasedTriggeringPolicy />
      <SizeBasedTriggeringPolicy size="250 MB"/>
   </Policies>
</RollingRandomAccessFile>

2. Added Logger:

<Logger name="com.pega.pegarules.integration.engine.internal.connect.rest.RESTconnector" additivity="false" level="info">
   <AppenderRef ref="RESTCONNECTORLOGS"/>
</Logger>

New log file with the name "RestConnector.log"  is created but System does not write Connect Rest request/response.

What am I missing?
