How to add a field to fill in wordpress category page (without plugins)?

Question

WordPress

Hello Toaster!
There is a description field on the category or brand page. The task is to add a field for a shortcode, banner, etc., and prioritize the field with description under the list of products so that it does not interfere visually and stuff SEO stuff there. Is there any tutorial on adding new fields in the category via function.php?

Look towards hooks
product_cat_add_form_fields- Adding a field on the create category page
create_product_cat- Saving the field value entered by the user
product_cat_edit_form_fields- Adding a field on the category edit page
edited_product_cat- Saving the value of the field entered by the user
