Designer: How to see file names?

Hi everyone,

I’m using Designer to create a simple animation on top of the tracking image. My animation has a transparent background so I’ve uploaded multiple videos on the platform to find one that become transparent when published… and I did!
However, all the thumbnails of the videos I’ve uploaded look the same and I have no idea which of the videos I’ve exported is working.
