Why when I use belongsToMany relation between two table not get the data

get data through belongsToMany relation between two table

Users Model :`

public function favorites(){

    return $this->belongsToMany('App\job','favourites',
                                'user_id','job_id')
                                 ->withTimestamps();
                           }`

job Model :`

public function favorites(){

    return $this->belongsToMany(job::class,'favourites',
                                'job_id','user_id')
                                 ->withTimestamps();
}`

Controller :`

public function index() {

    $jobs = Auth::user()->favorites;
    return view('home',compact('jobs'));
}`

nothing appears any errors and any data
