Fading FX on scroll

As the tittle say: I try to acheive some fading fx on scroll like on that web page: https://www.menuiseriembg.ca/ebeniste.php
See how the background image get reveiled from black backgroud color to more transparant as you scrooll down, is that possible with Wappler or shoudl I do this manually?

Thank you for your help.
