is there a direct explanation for each google-ads.yaml item?

Question

I am looking for collect data from Google ADS API into GCP by using Python scripts and it requires to fill these items for authentication in the google-ads.yaml file:

developer_token:
client_id:
client_secret:
refresh_token:
login_customer_id:

I was able to fill these items by asking people in my company or generating it with google python scripts in GitHub but I need to understand the role of each, the docs seems to be disperse with a long learning path.
