Purpose and difference of three JSON files(examples/refinement/samples) used the in BigQuery Data Loader

Hi team,
would you explain the purpose and difference of the three JSON files(examples.json, refinement_examples.json, samples.json) used in the BigQuery Data Loader?

As I understand it, the examples.json file is required for improved Gen AI prompting. However, I'm not clear on why the other two JSON files are also required and what kind of distinct data should be prepared for each.

Given that my previous tests indicate that all three JSON files are not optional, it would be helpful to include detailed descriptions for each file in the README file. This would greatly enhance clarity and understanding.
