To embed your Figma prototype do the following steps:
1. Make sure you have your prototype open and click that blue SHARE button on top.
2. Now select < > Public embed next.
3. Copy the code from the pop up and paste it into one of the embed code boxes in your journey map or persona. It will take a few seconds to load and then it will render your prototype like this.
You will also have a possibility to scroll within that iframe and also zoom in and out or show it fullscreen by hovering over the iframe and selecting appropriate actions.
The prototype will refresh every time you refresh the page with the map and all new changes made in Figma will reflect in the iframe.
