The Twitter get email address rule does not work with Oauh2

[KenEucker]

I agree with the Auth0 Code of Conduct.

Description

The get email address from Twitter rule only works with Oauth 1.0 and Twitter v2 uses Oauth 2.0.

Reproduction

This code:
(from: https://github.com/auth0/rules/blob/master/src/rules/get-twitter-email.js#29)

...
const _ = require('lodash');
const request = require('request');
const oauth = require('oauth-sign');
const uuid = require('uuid');

const url = 'https://api.twitter.com/1.1/account/verify_credentials.json';
...

Produces this error:

When using the new Twitter API and attempting to get email addresses with user logins, which you can log into without issue not using this rule:

Environment

• Version of this library used:
  vLatest from the "Enrich" rules from the Auth0 dashboard:

• Version of the platform or framework used, if applicable:
  IDK
• Other relevant versions (language, server software, OS, browser):
  N/A
• Other modules/plugins/libraries that might be involved:
  N/A

** Next Steps **

I am going to attempt to come up with an Oauth2 solution because I can't find anything on the internet that addresses this. I also searched this repository for mention of this issue but found nothing. I would welcome any collaborations or help or just feedback in general on this topic and if/when I get a working solution I can provide a PR for an additional javascript rule file for the Oauth2 flow.

Followup on this: it seems that the Twitter API V2 does not support a way to retrieve the logged-in user's email address. I have posted a comment on a topic which talks about this issue:
