Hello,
The category page is edited in Dashboard > Products > Categories > Edit category.
Edit Category page has additional options as follows:
Image for category heading allowing to set an individual image for a category page;
Image (icon) for categories navigation on the shop page – Categories in page title
Icon to display in the main menu (or any other menu through the site)
The rest settings are configured in the Theme Settings > Shop or Shop page. The category page is not editable and inherits all the settings of the Shop page.
You can create an awesome description in WP Bakery page builder and insert by means of HTML block https://xtemos.com/docs/woodmart/html-blocks-2/#cat_att_tag
Best Regards
