Describe the feature you'd like to request

Amazon Cognito released support for localization for a few languages. It would be nice to optionally force the locale when using signInWithRedirect

https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pools-managed-login.html#managed-login-localization

Describe the solution you'd like

type Language =
  /** German */
  "de" |
  /** English */
  "en" |
  /** Spanish */
  "es" |
  /** ... others */
  "..."

interface AuthSignInWithRedirectInput {
  customState?: string
  options?: {
    preferPrivateSession?: boolean
    lang?: Language
  }
  provider?: AuthProvider | {
    custom: string
  }
}

import { signInWithRedirect } from "aws-amplify/auth"

// force spanish
signInWithRedirect({
  options: {
    lang: "es",
  }
})

@HuiSF

I am also trying to signInWithRedirect with parameter lang=de.

I saw a discussion like this
#13861
#13892
Is it valid?

I wonder when the signInWithRedirect feature with custom query will be officially released?. It would be great if you could give me a hint.

Thank you
