Replaying a Storyline Animation Trigger?

Hi all. I created an animated diagram in Storyline, published it, and added it to my Rise course using the Storyline block. I ran it by our accessibility expert and it reads just fine with a screen reader (just FYI). I'd like to add a trigger to the slide that replays the slide when a user selects a Replay button. I tried reset timeline and restart course but none of them worked. Is there a custom trigger that would allow users to replay an animation? I've attached the story, if that helps. Thanks!
