Just a heads-up: On desktop, in all of the demos, I get stuck on the "Upload ID" step. Clicking on any of the buttons triggers the following error in the console:

Firefox: > Uncaught (in promise) DOMException: The object can not be found here.

Chromium: > Uncaught (in promise) DOMException: Requested device not found

Both at DocumentOptions.svelte:34

It tries to open the camera on mobile.

This should probably offer the option to upload a file, but at minimum it should handle the error.
