More documenation for Ready API using AI

I am looking for more documentation for Ready API using AI (Smart Assertion Engine). All I have are these web site pages:

https://smartbear.com/product/ready-api/features/api-testing-features/ai-test-creation/

https://support.smartbear.com/readyapi/docs/testing/assertions/reference/property/smart-assertion.html

Is there any more documentation (I would like more details)?

Also, is this "AI" feature enabled in a specific version of Ready API?  I have version 3.40.2 for now.
