How to return user data in API Platform JWT auth

Question

I have a difficulty, and I've been wandering around the internet for a while looking for the solution.

I'm using API Platform with JWT authentication, following the steps in https://api-platform.com/docs/core/jwt/ and it works really well. But I need to know if I can return the user data in the response, along with the Token, because I need to use it in the frontend. I really can't find how to do it, neither in the official documentation, nor by analyzing the bundle itself.

Is there any way?

Not sure if this is best practice, but you could create a custom Event Listener, one that uses the Lexik Authentication Success. That returns the token information

<?php

namespace App\EventListener;

use App\Entity\User;
use Lexik\Bundle\JWTAuthenticationBundle\Event\AuthenticationSuccessEvent;

class LoginSuccessListener
{

    public function onLoginSuccess(AuthenticationSuccessEvent $event): void
    {
        $user = $event->getUser();
        $payload = $event->getData();
        if (!$user instanceof User) {
            return;
        }
        // Add information to user payload
        $payload['user'] = [
            ...
        ];
        $event->setData($payload);
    }
}

And then in your services.yaml, you'll need to register the Listener

#services.yaml    
App\EventListener\LoginSuccessListener:
