My `90-acl.conf` file looks like:

    plugin {

      #acl = vfile:/etc/dovecot/global-acls:cache_secs=300

      #acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext

      acl = vfile

    }

    # To let users LIST mailboxes shared by other users, Dovecot needs a

    # shared mailbox dictionary. For example:

    plugin {

      #acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes

      acl_shared_dict = proxy::acl

    }

When ACLs were set for particular mailbox I can see that dovecot-acl file were created but I have no idea how to specify a pattern for shared folder like is in the `dovecot-dict-sql.conf.ext`

    map {

      pattern = shared/shared-boxes/user/$to/$from

      table = user_shares

      value_field = dummy

      fields {

        from_user = $from

        to_user = $to

      }

    }

My goal is to control how it appears on the client site. As for now is as `shared/user@domain/folder/` but I have no idea where it is defined.

Thanks,
