Multiple languages and detect user language in passwordless Lock login

I have a passwordless custom SMS gateway with Classic Universal Login experience.

The template for the login is based on Lock (Passwordless).

Right now I configured a language using the language option and some custom sentences using the languageDictionary option.

However I would like to make some change:

  1. Is it possible inside Lock to detect the user browser language?
  2. If so, how can I archive that?
  3. Finally, is it possible to pass this language to the request that Auth0 send to my SMS server?

Thank you in advanced for your help.

Any help on this please?
