Symfony 5.4 - How am i supposed to properly start mercure using symfony

I installed mercure using the following command as stated in the documentation:

composer require mercure

After that, i'm supposed to start the mercure server and here is the issue: how?

Symfony's documentation doesn't state that.
Mercure's documentation also doesn't state anything about it, especially using a config file generated in /config/packages/mercure.yaml.

What i've found is that i need to download a separate binary (for my specific platform) and then i'm supposed to start the server from Powershell using the following:

.\/bin/mercure run

However, if i try to pass -envfile ".env", then it doesn't even try to use any of the variables inside.
On top of that, it doesn't seem to be using any environment variables at all, even ones i've defined in cmd.

There are other things like how do i allow CORS, as there isn't something i can change in my config file, it isn't an argument i can pass to the binary and i can't add it as an environment variable.

if i ever try to subscribe to the event (which is done on port 2019 cause of the previous issues), 404 and CORS is returned.

also this is what i get with just .\/bin/mercure run:

My .env:

Right now i'm wondering how am i supposed to use mercure, i've looked at a couple videos for symfony 5.4 and they basically either are on linux and it somehow work for them OR It's marked as outdated cause of configs changes, syntax changes and others...

The documentation also doesn't help at all in that regard which kind of make me regret trying to use mercure.

EDIT:

I was told to try fiddling with Caddy configs, but it doesn't seem like mercure is trying to use those either, even tried specifying the config with -config.

Result:

• Port not set to 3000
• No allow_cors header

Caddyfile:

    # Learn how to configure the Mercure.rocks Hub on https://mercure.rocks/docs/hub/config{    {$GLOBAL_OPTIONS}    http_port 3000    https_port 3000}localhost:3000route {    encode zstd gzip    @origin header Origin http://localhost:8000    header @origin Access-Control-Allow-Origin "http://localhost:8000"    header @origin Access-Control-Request-Method GET    header Access-Control-Allow-Credentials "true"    mercure {        # Publisher JWT key        publisher_jwt "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJtZXJjdXJlIjp7InB1Ymxpc2giOlsiKiJdfX0.iHLdpAEjX4BqCsHJEegxRmO-Y6sMxXwNATrQyRNt3GY"        subscriber_jwt "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJtZXJjdXJlIjp7InN1YnNjcmliZSI6WyIqIl19fQ.0J4jgLQSHzPMTZ5jiYM8Yv7jmTANRgILG5FKY98LgEU"        publish_origins *        # Extra directives        {$MERCURE_EXTRA_DIRECTIVES}    }    respond /healthz 200    respond "Not Found" 404}

at this point, i feel like i'm using every tricks in the book and it still doesn't work, i'm probably gonna end up moving to periodic fetch instead, reliable and actually work.

Update:

• Server Start on port 3000
• CORS is now allowed
• 401 whenever i try to request a topic
