Hello,
Thank you very much for choosing our theme and for contacting us.
Product tabs are the Woocommerce functionality. Our theme suggests one additional tab globaly (congirued in the Theme Settings) and one and the same for all products; and one tab localy which is configured in the product page. You will find more information here: https://xtemos.com/docs/woodmart/product-page-options/
If it is not what you mean, you will have to search for a plugin.
Best Regards
