Z-wave Zipato keypad, How to register a new keycode/tag with the default ZwaveJS component?

I just migrated from the old legacy z-wave integration, in old integration had the option to display and show enrolled RFID tags and add them to the new slots.
The new ZWaveJS integration does not seem to have any support what so ever to display these enrollment RFID keys. Does anyone know or have a solution how I can add a RFID tag to my Zipato Mini Keypad ?

I know the ZwaveJS2Mqtt has a control panel where this can be managed, but I don’t want to start again from scratch, I have over 30 z-wave devices so I really want to stick with my current setup.
I’m running my instance on a NUC machine running HassOS, can I install ZwaveJS2Mqtt docker image on a separate machine and instruct it to connect to my existing ZWaveJS instance via websocket on port 3000 ? And then use Control Panel to manage the keycodes ?

Since I do not have any Zwave Lock on my Zwave network the Service zwave_js.set_lock_usercode
is not available.

I’ve also noticed the Service zwave_js.set_value, could I somehow craft a command which could set usercode/RFID tag to a specified slot ?

Any help would be greatly appreciated,
Cheers
