How to make scrolling (fix position) to the footer in figma?

Question

Figma

I made a side menu, fixed it so that the rest of the page scrolls. The question is: how to make the menu stop fixing when scrolling to the footer?

Answer 1

I honestly tried to do this, but Figma does not allow scrolling the frame down if this one has already been saturated to the end, and writing some scripts is also impossible. I made a crutch, but there you need to click on the area to see the footer, and to be honest, this is some kind of hat)
I would suggest covering the menu with a footer, well, or hammer it - after all, this is a prototype, not a finished layout)
