Close Storyline topbar item and continue course

Hi everyone, 

I am currently working on a storyline 360 training that has one main scene that the learner needs to go through. However, for some slides, the learner needs additional infos (some reports) that I have put in the right topbar. It is super easy to access the reports by clicking on them. Unfortunately, I don't know how to add a close button that brings the learner to the slide of the main scene that he/she stopped at. Is there any way to do that?
