UPDATE: I just tried to follow my own directions and sometimes a platform changes its process slightly. I ended up having to present the results which opened a new tab and I then copied that URL - which worked. Just an FYI, if you are having problems.
Thanks for that update. At first I followed your video and it didn't work but with the updated instructions it now works but I can only embed one question from a full survey instead of being able to click through an entire survey.
