How do I work with Synfig animations in Unity?

Hi, I'm working on my first 2D game, and I have some doubts about vector animation. I want my main character to have kick and punch animations, I've done some research and it seems like vector animation is the way to go. I am starting to work with Synfig, but before I start doing some animations, I would like to know how I could use them in Unity. I have no idea on how this works, so I don't know which format would be the best to export them, or if you can even work with these animations in Unity. Any help would be appreciated. Thanks
