Struggling in getting either to build a feature (ChatGPT) - suggestions?

Maybe it’s my prompting, but part of my webapp is having OpenAI’s ChatGPT integration - basically a wrapper. Even have the page for /chat - providing it screenshots, templates, it has the API keys, but prompting either the Agent or the Assistant to build out say a ChatGPT chat page using similar UI/UX - always a blank page.

Any suggestions?
