Lottie Animation Timing Controlled by Scroll

Hi everyone,

I’m looking to create a website opening page like this one - https://www.bikebear.com.my/

One where the scroll controls the timing of the Lottie. Not that the scroll makes the lottie play, but it specifically controls the frame by frame playback. Is anyone able to help with this?

*Disclaimer, I realise that may not be the method they used for their website but for my purposes, that would be enough
