BelongsToMany take 1 .

hi . I have two models and pivot table..

See the relations.

Cat.php

class Cat extends Model
{

    public function videos()
    {
        return $this->belongsToMany( Video::class, 'cat_video' )->withTimestamps();
    }
    
    function videoOne()
    {
        return $this->videos()->orderBy('created_at', 'desc')->take(1);
    }

}

Video.php

class Video extends Model
{
    public function cats()
    {
        return $this->belongsToMany(Cat::class, 'cat_video');
    }

}

I want to get the latest video at each category ( cat. ) .

$cats = Cat::with('videos')->get();

It returns videos ..

$cats = Cat::with('videoOne')->get();

It returns nothing ..

how can I get it ?
