Is this library supports login without identifier?

[tomocrafter]

Like GitHub, some web sites supports login without identifier like email. When residentKey is required, client can discover associated credentials itself so backend doesn't need to return allowedCredentials
I want to achive like this but it seems this library requires identifier on routes POST /webauthn/auth/options (

laravel-webauthn/src/Http/Controllers/AuthenticateController.php

Line 25 in 3368d17

$user = $this->createPipeline($request)->then(function ($request) {

)
