How to use SVG images?

If you have your SVG image as a file, like this one:
https://s.cdpn.io/3/kiwi.svg
then you can just insert your image's url into any of our image options, like into the image layer's "Image" setting.

But if you have your SVG image as a HTML code, then you should use the HTML layer (only available in the PRO version), where you can insert any HTML codes.
