Multiple rise courses embedded into storyline

Hello all,

I have a storyline 360 course that I am creating that will have numerous rise courses within it as web objects. I will have the courses embedded into the slide, but I need help figuring out how to get the trigger to work with those web objects. I need the "Next" button to become visible when the web object has been completed.

Is this possible? I cannot seem to find any trigger that works with web objects. Please help!
