Demonstrates how to refresh a Wish OAuth2 access token.

  // See Global Unlock Sample for sample code.

  // See Get Wish OAuth2 Access Token 
  // for sample code showing how to obtain a Wish access token for desktop apps.

  // This example assumes we previously obtained an OAuth2 access token for Wish.

  // Note: In most OAuth2 implementations, the token endpoint is the same for both the
  // refresh request and the exchange-code-for-token request (which happens when getting
  // the OAuth2 token for the 1st time).   Wish uses a different URL for the refresh:
  oauth2.tokenEndpoint = 'https://merchant.wish.com/api/v3/oauth/refresh_token';
