Dumpster in Carbonio

Hello!
In Zimbra, we had the option to recover deleted emails from the Trash via Webmail, with the "Dumpster" feature enabled, via the user's own webmail.
In Carbonio, this option does not exist in Webmail, even when Dumpster is enabled via CLI.
The Dumpster email can be restored via CLI. (Example: zmmailbox -z -m teste@teste.com recoverItem 499 Inbox)

Is it correct not to have this option via Webmail?

If so, will it only be available in the future?
