Convert horizontal scroll to vertical scroll

I´m trying to solve a UX problem of my portfolio site and hope somebody can help:

On my site, when you scroll down to the projects, you have to continue scrolling down to see all projects. It’s built like all the webflow-horizontal-scroll sites.

I experienced some people who wants to scroll horizontally to see all the projects. But of course this won’t work. Bad UX design…

My idea was to implement a script which converts horizontal scroll to vertical scroll.
Can somebody help?

Thank you!
