Fakro ZRF12 12 group remote association Qubino Flush Shutter

I have a SmartThings v2 Hub where I have included a Qubino Flush Shutter and a Fakro ZRH12 remote as secondary controller

I need to associate these 2 so a can control the Shutter relay with the remote. Later also 2 other Fakro ARZ Zwave rollers.

I found the Edge Drivers Shared by M.Colmenarejo and was able to install them.
I can switch driver for the remote and also for the shutter relay.
Now the part to associate them:

What I believe is:
Associate the Fakro ZRH12 to the Qubino so I switch the driver of the remote.
in APP open Remote, goto settings and select Device Association Groups Configure

  • Group number 1
  • NodeID: Network ID of Qubino 0F
  • Endpoint to Set ??(Default 0)
  • Single/Multi Channel device???
  • Select Set
  • Execute (I also tried with setting the remote in Learning mode during this time)

In HomeAssistant this is enough.

What am I missing here?
