Hi Pami!
Great question! The Next Big Idea Club courses' main menu page includes buttons to connect you directly with the Next Big Idea Club and their bestselling authors. While this main menu page can’t be recreated, you may be able to spin up something similar in the first lesson of your course. You can combine custom button blocks with interactive elements to link your learners to relevant content!
I have seen others interested in adding their own product information in a similar format. We've added this as a feature request and will be sure to notify you if we have any updates in this discussion.
