Hello, help me to set the default locale , but should not be displayed in the url
i also use this extension https://github.com/mcamara/laravel-localization, there are middlewares,
here is my router
Route::group([
/* 'prefix' => '{locale?}',*/
'middleware' => [ 'setLocale' ]
], function()
{
Route::get('{locale?}/real-estate/{slug}', [Modules\Realty\Http\Controllers\MainController::class, 'show'])->name('realtyvue.item');
});

here is my middleware setLocale

public function handle(Request $request, Closure $next)
{
URL::defaults(['locale' => LaravelLocalization::setLocale()]); // en, uk, pl
return $next($request);
}

when local == uk
http://domain.loc/uk/real-estate/17-shop Great result!!!! 200 ok

when local == pl
http://domain.loc/pl/real-estate/17-shop Great result!!!! 200 ok

when local == en
I need the default language not to be displayed in the url
in middleware
URL::defaults(['locale' => null]);

in vue
http://domain.loc//real-estate/17-shop Wrong bad result!!!! 404 error

and the result should be
http://domain.loc/real-estate/17-shop Great result!!!! 200 ok

Please help me to set up ziggy or laravel correctly when 'locale' must be null
