How can i restore an animation that i accidentally exported with another animation?

I made two animations and the names were similar so i accidentally exported one over the other. It took me a really long time to finish that animation so i'm desperate to get it back, i tried looking for similar problems on the dev forum and i found this site

https://devforum.roblox.com/t/i-just-accidentally-exported-an-animation-over-one-i-wanted/192452/8

I was told to run this script in the command bar

local id = 3735424173 for i, v in next, game:GetObjects("http://www.roblox.com/asset/?versionid="..id) do v.Parent = workspace:FindFirstChild("AnimSaves",true) or game.ServerStorage end

I've never really used the Save or Load buttons in the animation editor but supposedly the code creates an old version of the Animation which i can load into the animation editor but nothing happens when i run the code. The post didn't specify where the animation appears so i'm not sure if it's even working.
