Need help with integrating font animation on scroll

Hi, person reading this,

I really like the font animation on scroll effect on Tennent Brown’s website ( Does anyone know how to incorporate this? Do I need to implement custom code or use Lottie for animation? I have the background gradient color change trigger animation, but it seems like Tennent Brown has the background color change trigger integrated with the font animation as well. As a beginner in Webflow, generally very confused, would be delighted for a point in the right direction. Thanks in advance.
