!!! Overview
If the [Authorization Server] can accept the [Access Token Request] values, the [Authorization Server] sends back an [{$pagename}] which includes:

* [Access Token]
* [OAuth Scopes] - If this attribute is not present, the user denied access to all scopes (yet still clicked "Authorize"). Your application must handle this case gracefully.
* [Refresh Token] __OPTIONALLY__ 
* [code_verifier] comparing it with the previously associated [code_challenge], after first transforming it according to the [code_challenge_method] method specified by the client.
