Need help configuring wall switch

After a long time of searching for wall switches which match those already placed in my appartment which support either z-wave or zigbee (not wifi/bt), I finally found:

The shipment arrived yesterday, and right now I have tried pairing and using the switch. It seems like the pairing was successful; however it does not seem to be functional. I waited a while for the interview to be completed (about 60min), but still it does not seem to fully work.

When I open the device details in the HA gui, it states:

Node ID: 20
Node Status: Awake
Node Ready: No 

In the overview table it will state

Device                Manufacturer          Model
Node 20               <unknown>             <unknown>

I am using the Z-Wave JS integration with the version (git commit): * Sun Sep 12 20:03:32 2021 -0700 445f28d and HA version 2021.9.7.

Does this device need to be specifically supported by Z-Wave JS? I thought that it should work in a generic way? Is there anything I can do for further analysis?

And also, since this is effectively the first switch I am using in HA, how would I interact with it, automation-wise? E.g. what would be the trigger? (Usually its something like a device state, this time it must be a button press however)
