Useful if scanner mode is set to .once, but needs scanner again (e.g. alert with an error was shown).

It's a nice feature to have, but are you able to find a better way to do it without using a Binding?

Well, I knew that I forgot somewhere to reply...anyway, nope, I wasn't able to find a better way to do that.

Almost a year later, this hack still works :)
