devd lid close event

Hello,
I have freeBSD 14 on Thinkpad x270,
I just did do a fresh install and installed dwm and slock
the issue is I want to make laptop lock screen whenever I close the lid

here is my /usr/local/etc/devd/lid.conf
```
notify 10 {
    match "system"        "ACPI";
    match "subsystem"    "Lid";
    match "notify"        "0x00";
    action "/usr/local/bin/slock";
};

```
here is my /var/run/devd.pipe when I close the lid

```
!system=ACPI subsystem=Lid type=\_SB_.LID_ notify=0x00 !system=ACPI
subsystem=Lid type=\_SB_.LID_ notify=0x00 !system=ACPI
subsystem=Suspend type=\ notify=0x03 !system=IFNET subsystem=wlan0
type=LINK_DOWN
```

what am I doing wrong?

Thank You
