How to update multiple rows in Laravel Nova?

Considering this code below which is an action applied to a Resource in Laravel Nova:

I can only update 1 row, however not multiple rows?

How do I fix the code to allow the ability to update multiple rows?

public function handle(ActionFields $fields, Collection $models)
    {
        foreach ($models as $model) {
            try {
                $inventory = $model->inventory_item_id;
                $quantity = $fields->quantity;

                // Logging used for debugging
                Log::info('UpdateAvailablity action called: $inventory: ' . $inventory . ', $quantity: ' . $quantity);

                $inventoryLevelAvailabilityController = new InventoryLevelAvailabilityController();
                $inventoryLevelAvailabilityController
->updateProductInventoryStockAvailable($inventory, $quantity);
            } catch (\Exception $e) {
                $this->markAsFailed($model, $e);
            }
        }
    }
