The configuration file storage location of the Unreal packaged program

I’m using the VaRest plugin in my project to retrieve API data, but by default, it logs both request and response data. I checked the plugin settings in the project settings and found that Extended Log is set to False by default. However, even after packaging, the application still logs the data. I also tested it with Extended Log set to True, and it still doesn’t work. I noticed there’s no Config folder in the packaged application folder, so I created one myself and put the settings in the DefaultEngine.ini file, but it still doesn’t work.

I have three questions:

1. Do I need to modify anything in the project settings before packaging the application?

2. If there are no settings before packaging, can I enable them in the configuration file after packaging?

3.Where should these configuration files be stored in the application? In the projectname/Config folder, the Engine/Config folder, or somewhere else?
