Multiple page on a single app/url website

Hello - I am trying to build our visual regression tests but I am currently stuck at the moment. Our web app contains 3 screens but technically is just a single app so the URL of it stays at /example.
So for page 1 - it needs to click Continue
page 2 - still needs to click Continue
page 3 - user can submit the form.

So I am thinking how can I test these three screens if they have the same URL. I can use the clickSelector but only until the second page.

Hope someone can help. Thanks
