Adding Z wave Node

Hello
I finally got it to work! And the node now comes up as it should, and I can control my light using the paper UI.

Next up is to configure the Dimming node to one of the channels on på In-wall sitch(2channel).

I`ve been reading some aboout it and found this:

Is this something I can do in the OH2 Paper UI, or is this only through the xml file?

If it is through the xml file, do I just write the commands(in the link, ofc with my node ID etc) and just save the file in the userdata folder?

Regards
Jørgen
