I'm looking for a way to automatically load all streams from a product when loading a product (product/category page) but can't seem to find a way to add this. I could add it as an extended attribute, but I would rather make use of the `$product->getStreams()` function.

I've tried the following but I couldn't figure out how to add an association through this method:

```
public static function getSubscribedEvents(): array
{
    return [
        ProductEvents::PRODUCT_LOADED_EVENT => 'onLoad'
    ];
}

public function onLoad(EntityLoadedEvent $event): void
{
    $product = $event->getEntities();
}

```
