OPTIONAL. Space delimited, case sensitive list of ASCII string values that specifies whether the Authorization Server prompts the End-User for reauthentication and consent. The defined values are: none, login, consent, select_account
The following example shows how to implement an `OAuth2AuthorizationRequestResolver` that customizes the Authorization Request for `oauth2Login()`, by including the request parameter `prompt=consent`.
The following example shows how to configure the `DefaultOAuth2AuthorizationRequestResolver` with a `Consumer<OAuth2AuthorizationRequest.Builder>` that customizes the Authorization Request for `oauth2Login()`, by including the request parameter `prompt=consent`.

<1> Configure the custom `OAuth2AuthorizationRequestResolver`

<3> If an `OAuth2AuthorizationRequest` was resolved than return a customized version else return `null`

`OAuth2AuthorizationRequest.Builder.build()` constructs the `OAuth2AuthorizationRequest.authorizationRequestUri`, which represents the complete Authorization Request URI including all query parameters using the `application/x-www-form-urlencoded` format.
For the simple use case, where the additional request parameter is always the same for a specific provider, it can be added directly in the `authorization-uri`.

The preceding example shows the common use case of adding a custom parameter on top of the standard parameters.
