Hello! Can you provide the origin source of messenger configuration for amqp queues, please? It's the beginning of "Configuring a Second Exchange" paragraph in this lesson, changing the configuration of messenger.yaml file.
I didn't find this in official documentation neither in results on php bin/console config:dump framework messenger command.

Hey Dariia M.

Yes it's not fully described in official doncumentation, not in config:dump. I think it is so because it's DSN based configuration but you can find it in source code <a href="https://github.com/symfony/symfony/blob/efbe75291869ab944c62b48de9a0c2257ccace8f/src/Symfony/Component/Messenger/Transport/AmqpExt/Connection.php#L80"> here </a>

Hope it will help you!

Cheers!
