Cooking and Chunking how does it work?

Hello,

I need to chunk my game into several sections due to console requirements.
I have found this guid: Cooking and Chunking | Unreal Engine Documentation

But it confuses me more then anything else.
I’m not able to create multiple chunks in the Asset Audit and I can’t find a way to propperly assign or remove any data from the one any only chunk 0. Which just contails all data.

Is there any usefull tutorial or guid available?

Thank you!
