Using the knowledge base of an Interactive avatar in the Streaming API

We have created an Interactive avatar recently, and on your website ( https://labs.heygen.com/interactive-avatar) There's an option for a knowledge base for the avatar and its working well on this webpage.

How can we use this exact knowledge base with the streaming avatar API? is it possible to use this knowledge base with the Demo you provided on your website for example? because I see in the code that there is a KnowledgeBase parameter but I am not sure what to pass to this parameter to get it to work.
