Bg video loading help

hey there.
For my next website, I would like to play with the bg video widget. I need to display a lot of videos with this but of course this is very limited because if the video weight (takes a very long time to load when u have more than 3 bg video on a webpage) so I would like to use some sort of code that will load the video only when it enters into the viewport. I know loadie.js but I dont know how to use it with Webflow.
Can someone help me with this please?
Thank you for your time.
Have a very nice sunday,

This maybe give you an idea about lazy loading
