Question to KadenceWP users. Would it be possible to activate a Modal (created in Kadence) in the course lesson with the Basic Guttenberg editor? If we could just add a custom CSS class: modal-trigger?

The modal can also have a custom open ID. The Custom Open ID setting lets you define a link ID to open the modal. However, keep in mind that the link needs a “modal-trigger” class too.

Ref: Kadence https://www.kadencewp.com/help-center/docs/kadence-blocks/modal-block/

If the answer is Yes then please allow custom class for links in the Guttenberg editor (Courses). This way we can give some more flexibility for courses content.

BTW: it would be awesome to add class to links in posts to have the modal popup available for admin directly from posts/Comments - admins could embed whatever they want there (promo, ads haha). I guess Elementor also allows to trigger modals via custom css class unless it won't work at all.
