One sometimes overlooked, but cool, feature in Figma is the ability to live embed designs or prototypes into webpages. For example, I've used this to embed live component previews within design system documentation.
Mostly you don't want to change the url that is generated through the share link but there are a few useful attributes you can append to the url query string to change the way the embed appears.
