Use with VSCode typechecking in .js files

Not sure if this belongs here, if it doesn't feel free to close.

I am trying to get typings working with a jsconfig.json file without going full typescript. Usually when packages are imported like this:

import Controller from '@ember/controller'

VSCode picks up the types correctly but for some reason when importing from ember-ajax a could not import module is raised by the ts server. This is true for import { AjaxError } from 'ember-ajax/errors' as well. Is it not supposed to work like this?

This is the guide I am following.
