Adding Sold-Out to Product & Single Product pages

I would like to add Sold Out to both the Product (shop page) & the Single Product page created using Elementor Pro. I am aware that there is a “product unavailable” label used as a default after selected the inventory option within Product settings of WooCommerce.

I installed the WooCommerce Sticker plugin but did not resolve my issue. I will also post a message on their page if available.
