Animated SVG Import not working

Hey everyone,

Super new to using lottie, and I come from a UI/UX background so am not super code savvy.
But I am trying to import an animate SVG into lottie, but when I go to preview or animate, the animated doesn’t implement within lottie. Any idea what I am doing wrong?

It’s a loading icon to put within a button in an app. I can’t attached the SVG here but here is a preview GIF.
