Cannot find module 'wix-crm'

I am trying to send a triggered email from the onOrderPaid event in the events.js file. I keep getting the following error:

Error loading web module backend/events.js: Cannot find module 'wix-crm' 
Require stack:
- /user-code/backend/events.js
- /user-code/stubmodule-that-does-the-require.js
- /elementory/node_modules/scoped-require/index.js
- /elementory/factories.js
- /elementory/create-app.js
- /elementory/cloud-grid-runner.js

which originates from this line:

import { triggeredEmails } from 'wix-crm';

I have tried making a public code file called emailtouser.js which contains just the code for sending a triggered email in hopes of getting around this error. This is the code in emailtouser.js file:

import { triggeredEmails } from 'wix-crm';
export function sendemail(license, contactid) {
  triggeredEmails.emailContact('licenseEmail', contactid, {
  variables: {
    licenseKey: license
  }
});
}

However I still keep getting the exact same error whenever this line is ran from the events.js file:

import {sendemail} from 'public/emailtouser.js';

How do I send a triggered email from the onOrderPaid event in the events.js file without getting this error?

As stated in the wix-crm API :
The wix-crm module contains functionality for working with your site’s contacts from client-side code.
The wix-crm module is unavailable in backend (server-side) code.

You need to use wix-crm-backend since events.js is a backend file.
