Show order Weight in checkout

-- url of the page with the problem -- : www.dailybread.co.uk
-- HikaShop version -- : 6.2.0
-- Joomla version -- : 3
-- PHP version -- : 8

I want the customer to see the total weight of the order during checkout.

This is due that we have different charges based on the weight and so it would help the customer to add or remove products.

Thank you
