The <info>%command.name%</info> retries message in the failure transport.

The command will interactively ask if each message should be retried
or discarded.

Some transports support retrying a specific message id, which comes
from the <info>messenger:failed:show</info> command.

    <info>php %command.full_name% {id}</info>

Or pass multiple ids at once to process multiple messages:

<info>php %command.full_name% {id1} {id2} {id3}</info>
