```console
$ kcli bounce --help
Administratively bounce messages in matching queues.
Each individual message that is bounced will generate a log record capturing the event and then be removed from the spool.
Make sure that you mean it, as there is no going back!
The bounce will be applied immediately to queued messages, and the directive will remain in effect for the duration specified, causing newly received messages or messages that were in a transient state at the time the directive was received, to also be bounced as they are placed back into the matching queue(s).
Usage: kcli --endpoint <ENDPOINT> bounce [OPTIONS] --reason <REASON>
Options:
--domain <DOMAIN>
The domain name to match. If omitted, any domains will match!
--campaign <CAMPAIGN>
The campaign name to match. If omitted, any campaigns will match!
--tenant <TENANT>
The tenant name to match. If omitted, any tenant will match!
--reason <REASON>

--everything
