Creating a Responsive Figma Prototype from Canva Mockups

Hi guys! I'm new. I'm trying to quickly take my flat, static mockups from canva and turn them around in figma to a responsive prototype (mobile app, MVP) in a couple of days for a potential investor. The AI feature isn't what I need based on a quick trial error, i'm assuming using the library directly in figma is the way to go? any feedback would be helpful
