New to Bricks, OpenAi API integration?

Hi! I’m new to WordPress and Bricks. I’m watching the Bricks - Getting Started (installation, Settings, Editing) video, and I hit the part where Thomas goes over API keys. I want to integrate my OpenAI API, but there was not a place for that in the Bricks settings menu. How do I do this? Do I do this through Bricks, or can I just do it through WP itself? Thanks!
