Is it possible to use a Lottie/JSON file as a preloader animation?

Hi,

My animator created a Lottie/JSON file for me to use as a page preloading animation on my site. It's a 1.5 second loop of a 300px sized transparent animation. I had requested a GIF as I've found instructions online to use a GIF as a preloading animation. However, the GIFs he keeps sending over are far too low quality for me to use. So I'm wondering if anyone knows if/how I can use a Lottie animation instead? I can't find any instructions, tutorials or information online about this. Thanks for any help that you can provide.

@dross Squarespace doesn't support JSON file. You can try embedding the json file and add inside a code block. Here's a relevant tutorial to follow: link
