Step 1

Update config/laravellocalization.php, add country names which will be used for subdomains, add subdomain key with value "germany":

                            'de'          => ['name' => 'German',                 'script' => 'Latn', 'native' => 'Deutsch', 'regional' => 'de_DE','subdomain' => 'germany'],

Step 2

Update RouteServiceProvider.php

                    public function boot(): void
    {
       $this->configureLocaleSubdomains();
...

protected function configureLocaleSubdomains()
    {
        // Define a dynamic pattern for the locale subdomain
        Route::pattern('subdomain', 'austria|germany|switzerland');
    }

    public function map()
    {
        $this->mapWebRoutes();

        $this->mapApiRoutes();
    }

    protected function mapWebRoutes()
    {
        // Load routes that match the locale subdomain
        Route::domain('{subdmain}.'.config('app.app_domain')) // Define subdomain pattern
            ->middleware('web')
            ->namespace($this->namespace)
            ->group(base_path('routes/web.php')); // Point to your routes file
    }

    protected function mapApiRoutes()
    {
        Route::prefix('api')
            ->middleware('api')
            ->namespace($this->namespace)
            ->group(base_path('routes/api.php'));
    }

Step 3

Add middleware LanguageToSubdomain.php

                    <?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;
use Mcamara\LaravelLocalization\Facades\LaravelLocalization;
use Route;

class LanguageToSubdomain
{
    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
       
        $host = $request->getHost();
        
        /// Split the host by dots
        $parts = explode('.', $host);

        // Check if the first part is the subdomain
        $subdomain = count($parts) > 2 ? $parts[0] : null; // Adjust based on your domain structure
        
        // for local testing
        //$subdomain = 'germany';
        
        // Retrieve the localization configuration
        $localizationConfig = config('laravellocalization.supportedLocales');

        // Get the default locale from Laravel's app configuration
        $defaultLocale = config('app.locale'); // This retrieves the default locale
        

        // if this is orig domain
        if(empty($subdomain)){
            LaravelLocalization::setLocale($defaultLocale);
            return $next($request);
        }
        
        // find language code for subdomain
        foreach ($localizationConfig as $key => $value) {
            
            if($value['subdomain'] == $subdomain){
               
                LaravelLocalization::setLocale($key);
                return $next($request);
            }
        }
        
        // if no subdomain found, use default locale
        LaravelLocalization::setLocale($defaultLocale);
       
        return $next($request);
    }
}

update Kernel and add this middleware:

                    'languageToSubdomain' => \App\Http\Middleware\LanguageToSubdomain::class,

Step 4

Add route group in your routes/web.php and put middleware:

                    Route::group([
    //'prefix' => LaravelLocalization::setLocale(),
    'middleware' => [ 
        //'localeSessionRedirect', 
        //'localizationRedirect', 
        'localeViewPath',
        'globalData',
        'languageToSubdomain'
        ]
    ], function()
    {
      Route::get('/',[App\Http\Controllers\HomeController::class,'index'])->name('home');

Then you can use your routes without any additional params

Step 5

Create subdomains in your cPanel to point to the root folder, for example

germany.mydomain.com => public_html
