This use case has three steps and applies to anyone adding elearning content in an iframe:

If I have an iframe with an elearning lesson that is a prerequisite, the user should not be allowed to select Complete and Continue unless they have actually completed the activity. To prevent the learner from skipping the lesson, the first step would be to allow us to hide the Continue button (for now can be hidden using custom CSS).

For the second step, the learner will need to be directed to the next lesson when they have completed the necessary content in the iframe. Each EzyCourse lesson has a unique URL and can be shown to the user in a pop-up designed in an elearning tool (such as Articulate Storyline). Upon meeting certain conditions in the elearning content, they will be shown the link and can navigate to the next lesson (which is only currently possible with non-prerequisite lessons).

For the third and most important step, when the user visits the next lesson, the previously visited prerequisite lesson is automatically marked as complete.

It is the third step that is a feature request. Can you please provide the option to mark a prerequisite lesson as complete upon visiting the next one without the use of a button? This is most helpful for sharing elearning content in an iframe that is not intended to be skipped by users.
