title: trait 'App\HasApiTokens' not found in Lumen
body: <p>I am running Lumen (5.6.3) (Laravel Components 5.6.*). I'm trying to build a Rest api using this tutorial(<a href="https://www.youtube.com/watch?v=eWoJ2YbdrWU&amp;t=5s" rel="nofollow noreferrer">https://www.youtube.com/watch?v=eWoJ2YbdrWU&amp;t=5s</a>). Here is my games.php code:</p>
  
  <pre><code>&lt;?php 
  
  namespace App;
  
  use Illuminate\Foundation\Auth\User as Authenticatable;
  use Illuminate\Database\Eloquent\SoftDeletes;
  use Bican\Roles\Traits\HasRoleAndPermission;
  use Bican\Roles\Contracts\HasRoleAndPermission as HasRoleAndPermissionContract;
  
  use Illuminate\Database\Eloquent\Model;
  
  class games extends Model implements AuthenticatableContract, AuthenticatableContract, HasRoleAndPermissionContract
  { 
      use HasApiTokens, Authenticatable, Authorizable;
      protected $table="games";
  
      protected $fillable = ['Team 1','Team 2','Score 1','Score 2','Game Date','Viewers'];     
  }
  </code></pre>
  
  <p>The error I get after running is:</p>
  
  <pre><code>PHP Fatal error:  Trait 'App\HasApiTokens' not found in C:\Users...lumen-api\app\games.php on line 14
  
  Fatal error: Trait 'App\HasApiTokens' not found in C:\Users\...lumen-api\app\games.php on line 14
  
  In games.php line 14:
  
    Trait 'App\HasApiTokens' not found
  </code></pre>
  
  <p>I did everything the same as the tutorial. I can't solve this error in part 2.</p>
