Aeotec Nanomote Quad - OZW sees it but needs more Domoticz support

[randomdune]

I purchased one of these devices :
https://aeotec.com/small-z-wave-remote-control

Its a tiny remote - with 4 buttons.
It supports short and long click for each of them.

The OZW Control panel correctly recognizes the device and passes it on to Domoticz. (See attachment zwave_device entry)
But in Domoticz under devices, it only shows up with one entry. (see attachment Domoticzdevice)

How can I help to expand this into all 4 buttons (to be recognized as 4 pushbuttons)?
If there's some way for me to contribute config/logs I would be happy to provide that information.

Under devices I am showing 6 devices\switches that are tied to this device. However only the top big\wide button works. The others dont do anything and if I try to use the button inside domoticz I get this error "Error sending switch command, check device/hardware !"
