According to the documentation, the log4j configuration file cannot be used correctly

[NikulovE]

Describe the bug
https://github.com/conductor-oss/conductor/blob/main/docs/documentation/metrics/server.md
By reading this document, I only know that I need to add environment variables such as:
LOG4J_PROP=log4j.properties
However, I don’t know what to do next to use this environment variable to make the log take effect.
New conductor oss was switched to log4j2 with XML files
Details
Conductor version: 3.19.0

To Reproduce
Steps to reproduce the behavior:
set env LOG4J_PROP=log4j.properties

Expected behavior
Split logs to conductor.log, server.log metrics.log

Additional context
outdated file https://github.com/conductor-oss/conductor/blob/main/docker/server/config/log4j.properties
