How to debug gatling script in Intellij using maven build

I have gatling script and its running using mvn gatling:test with parameters

Intellij version 2021.2 and scala, maven plugins installed.

I am not able to debug the scenario scripts. Even though put mvn debug goal settings to local host 8000 pprt.

Can anyone please explain how to debug gatling scripts step by step.

You can’t debug step by step, in particular as such debuggers only work with blocking architectures.
You can lower the logging level in logback.xml
