Adding quizmaker quiz to wordpress

I have an old html site that I built a few years ago with a variety of quizzes created only for fun, not scorm or anything fancy. Getting them to run was a doddle, although they are not responsive below about 770px. I never worked out how to get them to run on mobiles properly, but the site didn't get a lot of mobile visitors so I wasn't unduly concerned. I built them with qm9, (I think that's the version) which a friend of mine has or had.

I debated simply transferring the original quizzes to the new site, which wouldn't cost me a cent, but thought I'd look at studio13 and (I assumed) get properly responsive output.

I uploaded the new suite13 to give it a run and to see if it would do what I wanted for a new site I'm building, based on wordpress. I've got to be honest and say I didn't see anything in the new program that I don't remember in the old version a couple of years ago, which was a surprise. However, creating the quiz was as easy as the previous version. Then I tried to install a couple of test quizzes into wordpress. Old and new versions.

All I get if I link to the quiz.html file is '404 page not found'.

Given that Wordpress is probably the most popular platform these days, I expected to find a simple 'how to' somewhere on the articulate site. I was wrong... there's absolutely nothing. Zero search results for wordpress. The only comments I have found have been on forums which appear focussed on selling a plugin which I assume is Articulate's, called 'embed articulate into wordpress' or similar, which costs €99 for a working version. I tried the restricted free download version from the wordpress plugin directory (max upload 3 files, are you sure???) but that doesn't give a responsive output either.

I can only assume I'm missing something. I thought the new studio13 would provide me with quizzes that would be responsive, but it doesn't. Although I can upload and run new and old quizzes onto an html site easily, I cannot do so on wordpress without paying €99 for a plugin that doesn't provide a better output than manually adding a url on an html site. There is no help whatsoever on the articulate site for wordpress users, which seems bizarre.

Can anybody tell me how I add a qm quiz to a wordpress page or post? And how do I make it responsive?

Thanks for any help you can offer.
