/**
 * @module OidcConsentBlock
 * OidcConsentBlock components are used to show the consent form for the OIDC Authorization Code Flow
 *
 * @example
 * ```js
 * <OidcConsentBlock @redirect="https://example.com/oidc-callback" @code="abcd1234" @state="string-for-state" />
 * ```
 * @param {string} redirect - redirect is the URL where successful consent will redirect to
 * @param {string} code - code is the string required to pass back to redirect on successful OIDC auth
 * @param {string} [state] - state is a string which is required to return on redirect if provided, but optional generally
