 * ```ts {5-8}
 * import { FacebookProvider } from "@openauthjs/openauth/provider/facebook"
 *
 * export default issuer({
 *   providers: {
 *     facebook: FacebookProvider({
 *       clientID: "1234567890",
 *       clientSecret: "0987654321"
 *     })
 *   }
 * })
 * ```
 *
 * #### Using OIDC
 *
 * ```ts {5-7}
 * import { FacebookOidcProvider } from "@openauthjs/openauth/provider/facebook"
 *
 * export default issuer({
 *   providers: {
 *     facebook: FacebookOidcProvider({
 *       clientID: "1234567890"
