How to make relation between 3 tables in laravel using laravel relation?

I have three tables:

SET NAMES utf8;
SET time_zone = '+00:00';

DROP TABLE IF EXISTS `api_credentials`;
CREATE TABLE `api_credentials` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `user_id` bigint(20) unsigned NOT NULL,
  `api_provider_id` bigint(20) unsigned NOT NULL,
  `access` text COLLATE utf8_unicode_ci,
  `created_at` timestamp NULL DEFAULT NULL,
  `updated_at` timestamp NULL DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `api_credentials_user_id_foreign` (`user_id`),
  KEY `api_credentials_api_provider_id_index` (`api_provider_id`),
  CONSTRAINT `api_credentials_user_id_foreign` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`) ON DELETE CASCADE,
  CONSTRAINT `api_credentials_api_provider_id_foreign` FOREIGN KEY (`api_provider_id`) REFERENCES `api_providers` (`id`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;


DROP TABLE IF EXISTS `api_providers`;
CREATE TABLE `api_providers` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `name` char(255) COLLATE utf8_unicode_ci NOT NULL,
  `table_prefix` char(255) COLLATE utf8_unicode_ci NOT NULL,
  `created_at` timestamp NULL DEFAULT NULL,
  `updated_at` timestamp NULL DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;


DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `email` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `email_verified_at` timestamp NULL DEFAULT NULL,
  `password` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `remember_token` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL,
  `created_at` timestamp NULL DEFAULT NULL,
  `updated_at` timestamp NULL DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `users_email_unique` (`email`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Here is my Model:

1. ApiCredential

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\Pivot;

class ApiCredential extends Pivot
{


    
}

1. ApiProvider

   
   namespace App\Models;
   
   use Illuminate\Database\Eloquent\Model;
   
   class ApiProvider extends Model
   {
   
       protected $fillable = [
           'name',
           'table_prefix'
       ];
      public function users()
       {
           return $this->belongsToMany('App\Models\User')->using('App\Models\ApiCredential');
       }
   }
   
   

2. user model

   
   use Illuminate\Notifications\Notifiable;
   use Illuminate\Contracts\Auth\MustVerifyEmail;
   use Illuminate\Foundation\Auth\User as Authenticatable;
   
   use App\Models\ApiProvider;
   use App\Models\ApiCredential;
   
   class User extends Authenticatable
   {
       use Notifiable;
   
       /**
        * The attributes that are mass assignable.
        *
        * @var array
        */
       protected $fillable = [
           'name',
           'email',
           'password',
       ];
   
       /**
        * The attributes that should be hidden for arrays.
        *
        * @var array
        */
       protected $hidden = [
           'password',
           'remember_token',
       ];
      
       public function apiProvider()
       {  
            return $this->belongsToMany('App\Models\ApiProvider','api_providers','user_id','api_provider_id');
       } 
   
       
        public function hasCredentials(String $apiProvider)
       {
         return $this->apiProvider()->where('name', $apiProvider)->get();
       } 
       
       
   }
   
   

**Now What I want:**
I want to get record from api_credentials table based on user and api_provider. Let say if I have three records in api_providers (names are adscane, cpalead, offertorro). I

I am running this function to get api_credential of `cpalead`.

    User::find(1)->hasCredentials('cpalead');

But it is not giving an expected result.

Can someone please help me to fix this issue.
