Where can I find the Figma prototype link?

1. Open the project with the prototype you want to test.
2. Click on the "Play" button in the top right of the screen.
3. Click on the "Share prototype" button in the top right of the screen.
4. Set the settings to “Anyone with the link” and “can view” to make it public.
5. Click on "copy link" and paste the link in the plugin.
