You can string together svg-containing frames in an interactive component, and use smart animate to do animated transitions between frames. But there is no Lottie-like feature built into Figma.

There also may be some plugins you can try out, but I have not used any of them to offer a recommendation.

Thank you. I already use your first suggestion but I was wondering if I could use an animated .svg in order not to duplicate my frames for every animation.

I will check if there are some plugins for this case.

Thanks again for your time!

I have found that the best way to play on prototype a .svg animation would be to use this SVG animation tool
