Add products without price to google product feed

-- HikaShop version -- : 6.3.0
-- Joomla version -- : 5.3.0
-- PHP version -- : 8.1.32

Hi,
Do you think it would be useful to have the option in the plg_hikashop_google_products plugin, to be able to select whether to also appear in the feed products that do not have set the price?
At the moment, products that do not have a price do not appear in the feed and I have a situation where I would like to at least be able to generate the feed with all the products, even if I then deactivate the option.
