Is there a wp plugin that can replicate that?

Hi,

do you happen to know of a wordpress plugin that could replicate what healthline.com has on its sidebar?

I mean making multiple ads fixed in the sidebar, every ad just for a certain amount of scroll depth.

Like that: https://www.healthline.com/nutrition/list-of-vegetables

I know there are plugins that can get your widget into a fixed position but couldn't find something like in an example.
