Gravity Flow approval page

I run a company intranet that is built using buddyboss and elementor. I am working on setting up an approval with gravity flow and the inbox is using the short code and looks fine. The entry page is a mess though. I can not figure out where to enable the gravity flow blocks so I can organize the view of individual approvals. The managers doing the approvals will get easily confused without a good UI.
Is there an issue with gravity view blocks and elementor? Where do I find these “blocks”. Is there a way to customize these pages with css?

There are documentation pages for the settings you can configure through blocks for Gravity Flow and the shortcode which you mention.

The entry details page - which your screenshot looks ot be from - would have most of its’ block settings defined in the detail view of the Inbox block (or Status block), and all of the pages, or markup/elements on them, are customizable via CSS yes.
