Hi, I've recently tried to install MultipleFileDelete JS for myself, I put the code in Special:Mypage/common.js but nothing happens, I tried the same in global.js, but nothing happened.

Can someone explain me how to install that JS?

importScriptPage('MediaWiki:MultipleFileDelete/code.js', 'dev');
