Switchbot Lock unlatch feature missing

Hello dear Home Assistant friends,
I just installed the Home Assistant Core on my Nas 220j.
purchased the bluetooth proxy and was successful able to integrate it to my HA.
integrating my switchbot lock was also successful. But I am missing the feature “unlatch” I know there are usually two options. One is to unlock the door and the second one is to unlatch the door.
I reinstalled everything twice and tried it again. everything is up to date. I am trying this for hours now. I really dont know what to do.
I am really suffering at this.
