Using your own Media gives Call to undefined method App\Models\Portal\Job::test()

[gsmember]

Hello,
I've setup a custom Media as per documentation.

Version:

"spatie/laravel-medialibrary": "^11.10"

config media-library.php:

...
    /*
     * The fully qualified class name of the media model.
     */
    'media_model' => App\Models\Media::class,
...

custom Media.php:

<?php

namespace App\Models;

use Spatie\MediaLibrary\MediaCollections\Models\Media as BaseMedia;

class Media extends BaseMedia
{
    public function test()
    {
        dump($this->collection_name, $this->disk);
        return false;
    }
},
...

my model Job.php:

<?php

namespace App\Models\Portal;
...
use Spatie\MediaLibrary\HasMedia;
use Spatie\MediaLibrary\InteractsWithMedia;
use Spatie\Image\Enums\Fit;
...
class Job extends Model implements HasMedia
{
    use InteractsWithMedia;
...

my code:

$temp = Job::first();
dd($temp->test());

error:

   BadMethodCallException 

  Call to undefined method App\Models\Portal\Job::test()

      Illuminate\Database\Eloquent\Model::__call()
      +13 vendor frames

      Illuminate\Foundation\Application::handleCommand()

other calls are working fine:

$temp->addMediaFromUrl($url)->toMediaCollection();

when I try this command:

$temp = Job::first();
dd($temp->getMediaModel());

I get:

"App\Models\Media" // app/Console/Commands/SyncJobs.php:110

Maybe I am missing something here. Your help is greatly appreciated.
Thanks!
