Interactive video with lightbox slides, problem how to resume video after pause

Hi everyone

I'm making an interactive video in Storyline. I have a lot of questions, with feedback, so I reated the questions on separate slides. In the video I added cue points. I created a trigger to lightbox a slide when the timeline reaches a certain cue point. I created a trigger to pause the video when timeline reaches that cue point. That seems to work. Problem I have now is, how can I resume the video after the user has closed the lightbox slide with a question? I can't create a trigger on my video slide using an object from the lightbox slide I guess. Shoudl I create a variable that that changes when the closing button of the lightbox slide is clicked?

Thx so much for your ideas!
