Nav Menu on right side with content scrollable in middle?

Hey, I am super new to webflow and need some help! I have this dream of a side nav menu that can bring me to certain sections on press.

I got this far but I want the body or content of the page to live in a scroll section. Basically just so the scroll bar is visible inside the content and not on the outside of the navbar that doesn’t even scroll.

However, any way I’ve gone about this the Nav Menu fails and won’t bring to the section or light up properly when I scroll past the section.

I basically have no idea what I’m doing but I’ve tried containing the body to 75VH and 100VH with scroll on also tried putting all the sections in a div with 100VH and scroll on. Both of these visually work but the function of the nav bar gets destroyed. Please help?
