How to log all requests and responses for Play Framework 2.5.x? - playframework-2.5

Question

I want to log requests and responses for my application. I expect they should be present in access.log file. However, my access.log file is empty. I have enables access logging in configuration.
Here is my prod-logger.xml :
<configuration>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${user.dir}/web/logs/application.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- Daily rollover with compression -->
<fileNamePattern>application-log-%d{yyyy-MM-dd}.gz</fileNamePattern>
<!-- keep 30 days worth of history -->
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%date{yyyy-MM-dd HH:mm:ss ZZZZ} [%level] from %logger in %thread - %message%n%xException</pattern>
</encoder>
</appender>
<appender name="ACCESS_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${user.dir}/web/logs/access.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover with compression -->
<fileNamePattern>access-log-%d{yyyy-MM-dd}.gz</fileNamePattern>
<!-- keep 1 week worth of history -->
<maxHistory>7</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%date{yyyy-MM-dd HH:mm:ss ZZZZ} %message%n</pattern>
<!-- this quadruples logging throughput -->
<immediateFlush>false</immediateFlush>
</encoder>
</appender>
<!-- additivity=false ensures access log data only goes to the access log -->
<logger name="access" level="INFO" additivity="false">
<appender-ref ref="ACCESS_FILE"/>
</logger>
<root level="INFO">
<appender-ref ref="FILE"/>
</root>
