请教：模型关联的问题?

请问images表如何同时关联User表和Admin表？
图片资源表：images

这是我写的关联方式

class Image extends Model
{
    protected $fillable = [
        'auth_model', 'model_id', 'name', 'path'
    ];

    public function user()
    {
        return $this->belongsTo(User::class, 'model_id');
    }

    public function admin()
    {
        return $this->belongsTo(Admin::class, 'model_id');
    }
}

public function index(ImageRequest $request)
    {
        $images = Image::query()
            ->with(['user', 'admin'])
            ->paginate($request->page);
        return $images;
    }

得到的结果

[
            {
                "id": 1,
                "auth_model": "App\\Models\\Admin",
                "model_id": 1,
                "name": "1.png",
                "user": {
                    "id": 1,
                    "name": "Echo",
                },
                "admin": {
                    "id": 1,
                    "name": "Admin",
                }
            },
            {
                "id": 2,
                "auth_model": "App\\Models\\User",
                "model_id": 1,
                "name": "1.png",
                "user": {
                    "id": 1,
                    "name": "Echo",
                },
                "admin": {
                    "id": 1,
                    "name": "Admin",
                }
            }
]

预期的结果是下面这样，我知道我写的关联方式是只能是上面的结果，想请教大佬们如何关联可以得到我预期的结果。😂

[
            {
                "id": 1,
                "auth_model": "App\\Models\\Admin",
                "model_id": 1,
                "name": "1.png",
                "admin": {
                    "id": 1,
                    "name": "Admin",
                }
            },
            {
                "id": 2,
                "auth_model": "App\\Models\\User",
                "model_id": 1,
                "name": "1.png",
                "user": {
                    "id": 1,
                    "name": "Echo",
                }
            }
]
