Forcing a Button Click in Rise

Hello. In Rise, I'm trying to force the learner to click a button to launch a web site before they are allowed to move on. But, it seems a button click doesn't qualify when you use the "Complete the content above before moving on" divider. The divider shows as a simple "Continue" divider before the button is clicked. Any thoughts on how I can ensure a button click before the divider allows the learner to continue?

Thanks.
