In the prototype I can't reach the bottom or the top of the page

I have a prototype of a website with a few frames of 900x1090. I zoom in to see the page at full width in a small monitor but now I can’t reach the bottom of the page, I scroll but stops before the end. If I zoom out I see the entire page again, then zoom in the bottom but then I can’t reach the top, this happens with every page in the same prototype.
I’m using Figma on browser Brave on Macbook.
