Laravel Custom PasswordBroker not sending password reset link email

I'm using customized password reset function in Laravel. Laravel version 5.8

I followed this document https://laravel.com/docs/5.8/passwords#password-customization And also adding custom guard I checked here https://laravel.com/docs/5.8/authentication#adding-custom-guards

I don't know what I'm doing wrong with these settings below.

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Authentication Defaults
    |--------------------------------------------------------------------------
    |
    | This option controls the default authentication "guard" and password
    | reset options for your application. You may change these defaults
    | as required, but they're a perfect start for most applications.

    */

    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    /*
    |--------------------------------------------------------------------------
    | Authentication Guards
    |--------------------------------------------------------------------------
    |
    | Next, you may define every authentication guard for your application.
    | Of course, a great default configuration has been defined for you
    | here which uses session storage and the Eloquent user provider.
    |

    | users are actually retrieved out of your database or other storage
    | mechanisms used by this application to persist your user's data.

    | Supported: "session", "token"

My Model extends authenticatable

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class CustomerLoginInfo extends Authenticatable
{
    use Notifiable;
    use SoftDeletes;

    protected $table = 'customer_login_info';

    protected $fillable = ['customer_id', 'login_email', 'password'];

    public function customer()
    {
        return $this->belongsTo('App\Models\Customer');
    }

    public function getEmailForPasswordReset()
    {
        return $this->login_email;
    }
}

Even though I get success message I don't receive password reset link email.

I'm using docker mailhog and I don't have any problem receiving other kinds of mails.

If you found anything weird in this code please let me know.
