Embedding survey into Thinkific webpage

I am fairly new to Qualtrics and am attempting to embed a survey through an iFrame into a course webpage hosted by Thinkific, a learning management software. Thinkific has its own next buttons that override the next button on my survey, causing participants to click out of the survey early and move onto the next page of the course. Does anyone know how I might require participants to interact with the survey? Ideally I don’t want participants to be able to click through the page until they have reached the end of survey. Are there other ways to embed the survey that might solve this problem? I reached out to Thinkific and they said currently they don’t have a way of fixing this on their platform. Thanks for any help!
