Hello. We're implementing a consent screen as an SPA with hydra, and I'm wondering how to go about protecting the hydra admin getOAuth2ConsentRequest/acceptOAuth2ConsentRequest api calls? At the moment I'm building a backend service that our SPA will call, which itself calls these APIs, that way the hydra admin apis do not need to be exposed. However I'm wondering if there's a pattern established, or best practices for protecting the hydra admin apis that are more-or-less required for public operation.
