Multiples video prototype

Hello,
i’m trying to build a prototype with multiple videos.

For each video i have a component with 2 variant : one is my thumbnail image, when i click it, it change to my second variant : the video with autoplay.
I also have a play/pause toggle when i click on the video variant’s.

Until now its ok. But i would like to pause or stop à video, when i play another one.
So i add a second event when i click the thumbnail : pause video 2. It doesn’t work at all…

Any idea ?
Thank you
