How to include the library in vue.js?

Question

Vue.js

It was necessary to integrate a search widget of one company into a project on vue.js. This widget is a js file that needs to be included and then called the init method.
This file does not work without jquery, and I have jquery connected via npm and imported in components that need it via import $ from 'jquery'.
How can I include a widget file? If I connect it via a script in the index.html file, then it swears that jquery is not connected.
Thank you.

import $ from 'jquery'

window.$ = window.jQuery = $;
