   Alternatively, it is possible to specify the `clientRegistrationId` on the request attributes and the `WebClient` will attempt to lookup the `OAuth2AuthorizedClient`.
   If it is not found, one will automatically be acquired.

  === Implicit OAuth2AuthorizedClient
  
  If we set `defaultOAuth2AuthorizedClient` to `true` in our setup and the user authenticated with oauth2Login (i.e. OIDC), then the current authentication is used to automatically provide the access token.
  Alternatively,  if we set `defaultClientRegistrationId` to a valid `ClientRegistration` id, that registration is used to provide the access token.
