Creating Workflow For Chat To Document Trigger

I am trying scade.pro out and after I’ve setup the API in bubble, I am completely lost. I don’t know to setup for API to get document, to ask it questions, and most important, how to display answers. Any help?

I would appreciate screenshots from staff with step-by-step tutorial and what should I write in the workflows. I hope I am not asking too much, this tool is wonderful! 10/10 on API tutorial btw!

Thanks,
