Downloading Video Wallpapers from Steam Workshop without using Wallpaper Engine?

Hey guys, so I recently made a switch from Windows to a MacBook for college and not having Wallpaper Engine supporting macOS is a huge loss for me. I recently found a program called Mach Desktop which has similar functions as Wallpaper Engine does but for MacOS and allows you to upload a video file to your desktop. Since I forgot to transfer all of my saved wallpapers from my Windows computer and can't download wallpapers from Steam Workshop via Wallpaper Engine (due to not supporting macOS) is there any other way I can download those wallpapers directly from the Workshop? If not, are there any recommended animated wallpaper websites with 4k or 1080 animated wallpapers? Thanks for your input!
