Out of stock products at the end of the category page - Magento 2.2.x

[mesk123]

I am running Magento 2.2.4 version and I need to display Out of stock products at the end of the categories page.

I have added the below code in vendor/magento/module-catalog/Block/Product/layer.php 

$collection->joinField('in_stock', 'cataloginventory_stock_item', 'is_in_stock', 'product_id=entity_id', 'in_stock>=0', 'left')->setOrder('in_stock','desc');

But its not working

Can anyone let me know how to display out of stock products at the end of the page?

Thanks.
