If you choose amqp interop based transport you won't need to dig into details at all. Only a few things to do:

Install enqueue/amqp-lib (btw you can use other transports based on amqp ext and a great bunny lib) transport and enqueue/amqp-tools.

composer require enqueue/amqp-lib enqueue/amqp-tools

Create amqp context, add a delay strategy and send delayed messages:

createContext();
$context->setDelayStrategy(new RabbitMqDlxDelayStrategy())

$queue = $context->createQueue('foo');
$context->declareQueue($queue);

$message = $context->createMessage('Hello world!');

$context->createProducer()
    ->setDeliveryDelay(5000) // 5 sec
    ->send($queue, $message)
;

By the way, this not this only strategy available. there is one based on RabbitMQ delay plugin. It could be used the same way.
