WooCommerce has hooks which allow sharing plugins to be added to your product pages either with plugins or in this tutorial, the following small code snippets.
Add the code to your child theme’s
functions.php file or via a plugin that allows custom functions to be added, such as the Code snippets plugin. Avoid adding custom code directly to your parent theme’s
functions.php file, as this will be wiped entirely when you update the theme.
