RISE Template no possible to edit

Hello Team

By chance I took the "Bradley Staats on How to Stay Relevant...." template to use in my eLearning, but there is a place "below a video section" that is impossible to use (the books pictures and the links below).

I open the Video section editor and I can modify the text below the video, but this section below the text is hidden for me and looks very nice to be used as a formation procedure.

Can you help me with this or this is a private "external resource"?

Thanks
