 You can implement this interface yourself or extend the *DefaultAccessTokenRetriever*. 
 
 :::note
-In Duende BFF v4, *DefaultAccessTokenRetriever* was made `internal`. If you need to customize token retrieval in v4, implement the *IAccessTokenRetriever* interface directly. The default implementation simply calls `context.HttpContext.GetManagedAccessToken()` with the configured token type, so replicating its behavior is straightforward.

 The *AccessTokenResult* class represents the result of this operation. It is an abstract class with concrete implementations that represent successfully retrieving a bearer token (*BearerTokenResult*), successfully retrieving a DPoP token (*DPoPTokenResult*), failing to find an optional token (*NoAccessTokenResult*), which is not an error, and failure to retrieve a token (*AccessTokenRetrievalError*). Your implementation of GetAccessTokenAsync should return one of those types.
