I would like to be able to embed a tourwriter proposal & itineraries into a webpage (not wordpress or with a link to my proposal)

different from https://www.ahipara.com/itineraries/new-zealand-luxury-itineraries

I think a script and iframe have to added on the html code of my webpage but i don't know what to do.

I have been able to do that with a travefy proposal, but i prefer the Tourwriter design ;)
