Hello there! Thanks for submitting your question. It's been awhile, but we hope this helps:

You can embed links in your web stories! So if you already have an animation saved to your LottieFiles workspace that you want to use, you can visit the Embed panel in your LottieFiles workspace after clicking an animation, and grab a copy of the animation's oembed code. Be sure to turn link sharing on, or it will not work.

We hope this helps, and please reach out if you have any other questions.
