Hello, I'm trying to use GSAP to play/pause a video. I saw a sample that uses the onToggle but I don't think that will give me the results I need because I might add a few items to a timeline and it seems like onToggle will only work if 1 item is on the timeline. Do you know how I can do this? I was also trying to use the .Call() method but I can't get it to work. Thanks
