I am using the latest beta version of Oxygen Builder (3.9 Beta 1), you need to make sure the frontend form shortcode, for my case
[mb_frontend_form id='details-of-the-company' post_fields='title,content' edit_page='company' allow_delete="true" edit="true" ajax="true"]
are inserted in the Guternberg editor. Although it does display the dashboard on frontend. But I couldn't see any post details on the dashboard.
.
