How to load custom .env file in Laravel console command?

I have this console command code:

class MyCommand extends Command
{
    protected $signature = 'custom:mycommand {domain}';

    // ...

    public function handle()
    {
        $domain = $this->argument('domain');

        // read domain based .env file, like: .env.example.com
        $dotenv = \Dotenv\Dotenv::createImmutable(base_path(), '.env.' . $domain);
        $dotenv->load();

        dd(env('APP_URL'));

        // ...

        return 0;
    }
}

In the line of dd() it should print the domain what I gave as parameter (coming from .env.example.com, but still print the data from .env file.

Otherwise this function is working well in AppServiceProvider with this code:

$host = request()->getHost();

// read domain based .env file, like: .env.example.com
$dotenv = \Dotenv\Dotenv::createImmutable(base_path(), '.env.' . $host);
$dotenv->load();

Any idea how can I make it work in console command?

Immutability refers to if Dotenv is allowed to overwrite existing environment variables.
If you want Dotenv to overwrite existing environment variables, use as Mutable instead.

This is how I used it.

   $env_name = $this->argument('env_name');
   if(!empty($env_name) && is_string($env_name)){
        $dotenv = \Dotenv\Dotenv::createMutable(base_path(), $env_name);
        try{
             $dotenv->load();
             $this->info(env('NAME'));
             $this->info('The Dotenv was loaded successfully!');
        } catch(\Dotenv\Exception\InvalidPathException $e){
             $this->error($e->getTraceAsString());
        }
    }
