Detect Language for spoken-to-signed language translation should identify the language of the input spoken language text.
If selected, when translating the text to SignWriting, first it should go through the identification model (should be client-side).
Additionally it should indicate the assumed language.
Unfortunately, afaik, the browser doesn't natively support it.
