Unable to obtain network-acl logs

When I want to send OVN logs to incus, I follow the documentation to configure it, but currently I cannot find the ovn logs in loki.
These are the relevant configurations of the cluster

root@hci01:~# incus  config show
config:
  cluster.https_address: hci01.service:8443
  core.https_address: hci01.service:8443
  core.syslog_socket: "true"
  loki.api.url: http://172.31.30.129:3100
  loki.instance: incus:clus-szqFwZzof1
  loki.types: lifecycle,logging,network-acl
  network.ovn.northbound_connection: tcp:172.31.30.129:6641,tcp:172.31.30.130:6641,tcp:172.31.30.131:6641

root@hci01:~# cat /etc/default/ovn-host

result

root@hci01:~# incus monitor --type=network-acls

I canโ€™t find the logs of network-acl and ovn on grafana, the types shown here are only lifecycle and logging.
What else do I need to do? Hope to get your reply.
