How can I get the Plugin Script for the Roblox Animation Editor?

It’s a built-in plugin so I don’t think it is possible and if it is, it probably won’t be straightforward.

You can’t do that It’s impossible.
It’s not even a plugin to be honest it’s just a part of studio

Click on windows + r, type appdata and click enter
Go to local > roblox and there, explore until you find it, you will be able to find EVERYTHING on all built-in plugins, sounds, images, even your own plugins!
This will have ALL appdata of roblox and roblox studio you MUST NOT change anything.
