Embed HTML code for virtual tour in Colibri not possible?

Hi, I would like to embed my virtual tours in calibri editor. In wordpress standard I use the HTML code and paste it in [/]
Wordpres has no page design. So it looks idd in combination with the well looking Colibri design. I would like to embed the virtual tour just like a video or image in Colibri design but cannot find the option to that.
Anybody any advise with what option I can embed HTML code in Calibri design?
