Horizontal and vertical scrolling

Hi all, I have the following setup I want to create, but can't get it done.
A horizontal scrolling of 3 sections, where the 2nd section stops to vertically scroll its content. When it reaches the bottom of the content from section 2, it continues to scroll horizontal.
The horizontal scrolling I did with a width of 300vw for the container of the 3 sections, which each has a width 100vw.
But how can I tell section 2 to stop and scroll its vertical content, before continue the horizontal scrolling?

Could anyone point me in the right direction on this one?
The pinned content in section 2 would be an extra question of how to ;)

Thanks,
Carola
