I saw this thread: [Adding an extra param to auth0 call](https://community.auth0.com/t/adding-an-extra-param-to-auth0-call/57720)

but how will i add the state parameter here:

```auto
Rails.application.config.middleware.use OmniAuth::Builder do
  provider(
    :auth0,
    ENV["AUTH0_EXTERNAL_RWA_CLIENT_ID"],
    ENV["AUTH0_EXTERNAL_RWA_CLIENT_SECRET"],
    ENV["AUTH0_EXTERNAL_DOMAIN"],
    callback_path: '/auth/auth0/callback',
    authorize_params: {
      scope: 'openid profile email',
      connection: ENV["AUTH0_EXTERNAL_DATABASE_CONNECTION"],
      state: ???????
    }
  )
end

```
