This is FSE block which can be used on Single product template and in query builder block.
It has only one simple purpose – it shows categories or tags of current product.
This is analog of core Product categories and product tags blocks. Difference is only in number of design options. Also this block has option to add custom labels before category list, postfix and prefix. Also, this block has inherited context from Woocommerce query builder so it will work faster in grid builder
