Fibaro Dimmer 2- not dimmable


I can see several posts discussing fibaro dimmer 2 integration. The problems seem similar to mine but they seem to discuss more stuff and o get confused. Hence the post. Please see the attached image . There is no dimmer option for the device after successfully adding it to SmartThings app. The device is recognised as a Z-wave device multichannel. This seems to be a reasonable device type from the various posts I read and should be good enough to have dimmer options but not for me.

Do I have to follow the custom code shared by Rajiv ? Or are there any other options for me?

The bulbs that I have used are dimmable
