Magento 2 show out of stock configurable product

Question

So i have furniture bed configurable product which has 4 simple products "Single | Double | Queen | King" if in the admin panel i set the inventory of "single bed" to 0 then "Single" option is not showing at all, i want is it to show "Single" in the frontend and as Out of Stock... so i can add email option later if available.

I tried "show out out stock items in frontend" but it only works for simple product not configurable

thanks

It might depend on the version you're using of magento if you're using an older one, that I think you are because that's a more or less feature you can try this https://github.com/interjar/configurable-child-visibility

If you're using a more recent version the should show out of the box with that option. But I must say, in the recent version of magento and without plugins most of the products they show the options even out of stock as intended but some just don't and I can't get why.

Hope it helps:D
