Hello,

I need to attach a custom header like "x-message-deduplication" to some messages I send to RabbitMQ thru Symfony Messenger. Can anybody give me a solution for this please?

If I create a custom Stamp and it generates me a header like this:

X-Message-Stamp-App\Messenger\DeduplicationStamp: [{"uniqueHash":"dewf8347wfh84fhcre87fh"}]

but I need the header like this:

x-deduplication-header: dewf8347wfh84fhcre87fh

How can I accomplish this? Thanks!
