I am trying to get the intro.js (https://introjs.com) javascript code to work on my Wix.com website, but I cannot get it to work.

I have the css file written into the header as described. I have installed the npm package using their "velo" developer mode to my website, and my "Home.js" has this code:

import introJs from 'intro.js';

export function button1_click(event) {
    introJs().start();
}

However, when I click the button (after having added an html element with data-intro), I receive this error:

ReferenceError: document is not defined

How do I fix this?
