As part of the Get Started for Tech Providers, the following instructions are suggested for validating embedded signup:

"To test Embedded Signup, simulate a customer completing the flow using a test customer's business credentials generated from your own platform. After completing the flow, verify that you are able to access the test customer's WhatsApp Business Account and send messages on its behalf."

Unfortunately as soon as I create a test business on the platform, and associate it with a whatsapp business account, it gets shut down and disabled, and cannot be used for testing. What is the expected method of going through the validation as a test customer?
