Edit Inventory page with WpBakery/Elementor
The page builders require a content area in the pages/posts you are editing as per the WordPress Codex guidelines. Post type, category, tag, and any other archive pages do not contain a content area and have a completely different structure. So, the archive page can’t be edited by the page builders (like Elementor and WPbakery).
See the below notification by Elementor while editing an archive page. It clearly indicates that this page does not contain a content area (technically
the_content function is not called here).
You can also see the same thing with the Blog or any other archive page.
