We have errors where we don't show the chooser i.e. when we can't ask for
permissions but we also have errors where we do show the chooser but the user
decided not to enable the permission.

Yeah, there's a chance this one did show the chooser, and that's when the user
decided never to let Chrome ask again. Do you have a better idea for the enum
value? It's a separate error message because the website needs to know that
calling requestDevice() either had or is going to have no effect, so the user's
going to think something's broken.

"UserDeniedPermissionToScan"?

Sure, done.
