What SetId value should be set in create customer account SOAP interface?

Summary:

I'm trying to create a customer via REST & SOAP APIs in Oracle Cloud ERP (referring to A Simple Guide to ERP Cloud Customer Creation through integration). And I found that in the first step creating an organization, I can also create Addresses which is actually Sites in the front-end. But customer site is not visible in front-end until I create an Account and bind a site to it. In the example below, I couldn't see Account Number 14015 and Site Number 15007 until I ran the SOAP request in Postman to create the account.

Questions:

1. in SOAP request, what is the legal value set for "CreatedByModule"? Where could I find such info?
