Absolutely please see the attached example which was sent to me by @TejusVenkatesh from UiPath - this has examples of handling user events. You can for example wait for someone to click the start button or a button within an application. Furthermore, you can add validation to forms by blocking the progress before you have checked the values that have been entered.

There should be a tutorial if you search the videos.
