Like (probably) everything imported from the asset store, ORK is not part of the package manager. You can remove it by simply deleting it from your assets folder.
Please consider rating/reviewing my products on the Asset Store (hopefully positively), as that helps tremendously with getting found. If you're enjoying my products, updates and support, please consider supporting me on patreon.com!
