When designing a guided tour that requires direct action, such as clicking on a specific link or filling out a specific text field or just clicking on a specific UI element in your app, consider removing the "Back" and "Next" buttons. This is most effective when teaching your users how to use a certain feature.
Create a guided tour in your app and after it is completed, log back in to UIQ App and navigate to Engagements -> All Engagements. Now scroll over to your newly created guided tour and hit edit as sown below.
You can remove the types of both the left and right buttons by toggling them off as shown below.
After doing that, as you can see in the preview on the right, there are no buttons on the guided tour step and the end user would have to actually click the specific tethered UI element in order to complete or continue the guided tour.
