Setting rollover strategy in log4j2.properties

Can anybody help me with setting the rolloverstrategy in log4j2.properties ? I have set it up as -

#Appender
appender.test.type=RollingFile
appender.test.name=test
appender.test.fileName=${logPath}/test.log
appender.test.filePattern = ${logPath}/test-%i.log
appender.test.layout.type=PatternLayout
appender.test.layout.pattern=%d{ISO8601} %-5p [%t] %m%n
appender.test.policies.type=Policies
appender.test.policies.size.type=SizeBasedTriggeringPolicy
appender.test.policies.size.size=1MB
appender.test.strategies.type=Strategies
appender.test.strategies.rollover.type=DefaultRolloverStrategy
appender.test.strategies.rollover.max=5

I wrote this consulting https://logging.apache.org/log4j/2.x/manual/configuration.html#ConfigurationSyntax

I didn't find anything for implementing rollover strategy and what you see above is what I thought would work.But unfortunately and obviously it does not.

Here is the error:
