LottiePlugin for Adobe Animate distorts the shape

Discord app does not supports lottie stickers with raster images, so I wanted to find easies way to publish animated pictures.
GIF to SVG to Lottie does not works.
GIF to MP4 to Lottie converter does not works.
So I decided to redraw emoji with Adobe Animate. I dont know how exactly Lottie works. I’m new at Animate.
So what am I doing wrong?
