mcamara/laravel-localization : usage and understanding -- need help

I'm trying to accomplish:

• no locale in url for the local set in config.php
• when a language is selected the local is set in the url

What I have in code:

kernel.php

    protected $routeMiddleware = [
// Locale REDIRECTION MIDDLEWARE
        'localize'                  => 'Mcamara\LaravelLocalization\Middleware\LaravelLocalizationRoutes',
        'localizationRedirect'      => 'Mcamara\LaravelLocalization\Middleware\LaravelLocalizationRedirectFilter',
        'localeSessionRedirect'     => 'Mcamara\LaravelLocalization\Middleware\LocaleSessionRedirect'

routes.php

Route::group(['prefix' => LaravelLocalization::setLocale()], function()
{
//------- ADD ALL LOCALIZED ROUTES INSIDE THIS GROUP -------//

Route::get('/', 'HomeController@index');
Route::get('home', 'HomeController@index');

Route::get('welcome', 'WelcomeController@index');

});

config/laravellocalization.php

    'useAcceptLanguageHeader' => true,
    'hideDefaultLocaleInURL' => true,

What is happening: The language selector uses code as per readme and will switch the url to "es/home" and will translate the page correctly. When I click on the link "/home" the language returns to English.

What am I doing wrong? Do I need to code or set my urls a certain way? If so would you mind providing some code?

I did look at the blog app that mcamara has in his repositories but it sets all urls as "en/home" or "es/home" which isn't really what I am trying to do so I didn't download and install to use as a learning source.

Thanks!
