Yes, this should work, but you’ll need the HTML “wrapper” to use the method posted in that thread. So, on the LottieFiles page, scroll down a bit to find the “Use this animation in” section and click the "<html> " button

If you copy the script from there into your Axure Cloud Plugin it should work.
…I’m still wanting to figure out a way to use the .json files directly without the need for Axure Cloud and the HTML wrapper.
