Webstorm move top level symbol to another file

The option to move a symbol to a new file is available in the context menu

However it is not available through refactor/move (the top of this article says it should be https://www.jetbrains.com/help/webstorm/specific-javascript-refactorings.html)

Seems that only move file is available, which moves the entire file to a different directory, and is not what I am looking for.

This is an issue for me because I am trying to extract a few top level methods to a new file
