We have a slightly outdated one, it's just not as obvious on that page as it should be. If you click the "Watch Slyde in Action!" it's actually a button. We have a pending update that embeds an updated version of that video.
If you can get in touch with the frontend person, please recommend that they use a link (A element) or button (INPUT element) to make the control, otherwise it is not recognized as clickable by some useragents.
I'm using serenade.ai to control the page, and it won't even let me scroll down or click buttons/links
