Why is orderBy('gebot', 'ASC') not working anymore here?

Second Question:
<?php
    $offers = Car::with(array('Bids' => function($query){
        $query->orderBy('gebot', 'ASC');
    }))->get();
    
    return $offers;
?>

How can I only return $offers that have at least 1 "Bid" from "Bids"? 
Is there a chance to do this with eloquent?
