Exporting simple walk animation PNG

Hey, as a school project I chose to make a simple videogame, and for animating my character I use Adobe Character Animator. I have set up my walking and all perfectly, but I don't know how to export it to become a spritesheet or a set of PNG's to import to Unity. The only solution I've thought about is to perfectly record the character walking and then exporting it, but I was wondering if there is a simpler way to do it.
