Lottie Animation on Scroll

Hello peeps,
I am currently trying to figure out a way to use Lottie Animations on scroll on landing pages.
I have been looking throughout the documentation but haven’t figured out a way to manage.
Here’s the dummy LP that I am using https://get.uberall.com/blank-page-19/

Let me know if you need further details regarding this!
Thank you so much for your help!

Best,
Andrea
