I want to add a timeStamp("app_logs_2023-05-15.log") in the generated log file from Log4J Java in my selenium project, but not happening

Question

I have tried with log4j.appender.file.File=logs/app_logs%d{yyyy-mm-dd}.log but file is getting generated with "app_logs%d{yyyy-mm-dd}.log" name. TimeStamp is not getting added.

Also tried with log4j.appender.FileNamePattern=logs/application_%d{yyyy-MM-dd}.log as well.

Any suggestion would be really appreciated.

log4j.rootLogger=INFO, file, stdout

# Direct log messages to a log file

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logs/app_logs.log   =====\>\> Need to updated this.
log4j.appender.file.MaxFileSize=10KB
log4j.appender.file.Append=true
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout.ConversionPattern=\[%3p\] %d \[%t\] %c %x - %m%n
