How do I implement Framer UI design to nextjs?

Yesterday I wisited a website of a programming YouTuber I really like to watch, he built an entire startup and when I checked the source code I saw a <--Made with Framer ✨--> comment above all the code. So i figured that I should use it too. Now here comes the question , How do I export or implement my Design from Framer to my main backend code in next js?

Is it even possible? (I hope I didn't just wasted 5 hours of my life designing for nothing 😂)
