Workday Audit Log ingestion method outdated steps

Hi ! 

I’m trying to ingest workday audit logs according to the google supported guide:

https://docs.cloud.google.com/chronicle/docs/ingestion/default-parsers/workday-audit#create_pubsub_topic

However, when I get up to step 2 in “Configure Workday Custom Report”, I am unable to find data source “Audit Trail - Business Process”, I have full access and license isn’t an issue. Is this an outdated data source name? If so, whats the new name / method for collecting these logs?

Also the guide notes storing WD_USER and WD_PASS into the container, is there another way for this to be complete ? Basic Auth would not be the best method in my opinion.

Thanks

Finn
