Captivate 9: video - how to start on user click

HI

I've inserted a .mp4 video onto a slide. The video is auto starting; however, I'd like the video to only start playing after the user clicks a play button.  I don't see where I can make this change on the Properties panel.

I inserted the video using these instructions:

1. Video -> Insert Video

2. Multi-slide sync'd video -> Browse (and then picked the .mp4 file I wanted)

3. Modify slide duration to accommodate video was checked off

I used these instructions as I need to add closed captioning to the video and was instructed that this was how I needed to set it up for the cc to work.

Thanks, Marion
