Post html code in text field (Virtual Tour 360)

Hello.  I hope all is well.  Has anyone figured out how to post html code in the text field?  I'm trying to post an embed code from Sketchfab (3-D samples) while using the Virtual Tour (360).  This could allow students to "manipulate" samples while in a 360 space.  So far I can only post videos, pictures, text, and questions in the tour.  I am aware that the Text box has a hyperlink feature, but that "kicks" students out of the 360 environment, which sorts of defeats the purpose.  Any help would be truely appreciated.  Thank you and have a great day.
