Fullscreen horizontal snap scroll page?

I making my own website and I wanted to create horizontal one with snapped behavior.
So it’s only three blocs. Landing page should be the middle one. On left side there will be a photography portfolio and on the right side video portfolio. Still I have no clue how to do it…
Can I modify Snap Scroll bric from blocs shop to do the trick? Should lern and use Temult Hype for that?

So I came across this page

example 4 is what I need but I have no clue how to implement code
