Implement my own Openai API into 8th Wall

Hi! I’m trying to use my own openai assistant API, where I can search from the documents I upload. For this I created my own secret key inside the ‘Default project’ and would try to copy it. This key is supposed to work with the documents I uploaded, would that be my API for the assistant I created? I’ve copies my secret key into 8th wall project, but it didn’t work, it still uses the general chat GPT, not my own assistant with the uploaded documents by me.

Do you have any suggestion how could I make an openAI assistant (with my documents) working in 8th wall? Thank you!
