Demonstrates how to refresh a token that was obtained using the authorization code flow. Lua

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- See Get Okta Access Token using Authorization Code Flow with PKCE
-- for sample code showing how to obtain an Okta access token using the authorization code flow for native apps (with PKCE).
