How to add custom video thumbnails to wp media library

Hi all,

I am trying to include vimeo videos in my WordPress media library.
I found the proper way to show a vimeo video in the attachment details screen:
wp.media.view.Attachment.Details.prototype.render.

I cannot find a way to replace the video.png image shown in the media librarry overview (https://localhost/wp-admin/upload.php).
How can I do that?
I can do it the ugly way via document.querySelectorAll('[src*="video.png"]').forEach(el=>el.src= but I rather do it properly.

Any help appreciated.
