As it is a personal-use only script per its documentation page, it can only go in your own personal JavaScript. You can add the import to either Special:MyPage/global.js here (for use on every wiki) or Special:MyPage/common.js on the particular wiki on which you want it.

As an added note, you may want to check and make sure JS is enabled via Special:Preferences.
