Twitter(OAuth2.0)

/**
 * Example of using Twitter Application-only authentication from Google Ads Scripts
 * Application-only authentication is used where the aspects of the API being
 * used do not require impersonating a given Twitter user.
 *
 * Example usage:
 *   initializeOAuthClient();
 *   // Get trends using a woeId to specify location. See:
 *   // https://developer.yahoo.com/geo/geoplanet/guide/concepts.html
 *   const results = getTrendsForLocation(44418);
 *
 * See https://developers.google.com/google-ads/scripts/docs/features/third-party-apis#client_credentials_grant
 * for details on configuring this script.
 *
 * NOTE: This script also requires the OAuth2 library to be pasted at the end,
 * as obtained from https://developers.google.com/google-ads/scripts/docs/examples/oauth20-library
