Feature: Parameter to pass a custom error message to the Auth0 hosted universal login.
Description: Currently it is not possible to pass a custom error message when calling the browser SDK loginWithRedirect method that is then displayed on the Auth0 hosted Universal Login.
Our login completely relies on the Auth0 hosted Login Page and we do not have any page implemented for not logged in users (and therefore no place to show error messages to login scenarios). Our current use-case is to block logins for non-verified users via Auth0 Flow which causes a redirect back to our application with ?error=access_denied&error_description= parameters and we want to pass this error to the Universal Login. Independent of this scenario, imho it is also useful for many other situations to pass an error message to the Universal Login page.
