Trying to use the dial on Stream Deck + for monitor brightness

I am trying to use my stream deck plus dials for monitor brightness but it doesn’t work for some reason. Does anybody have a tip how to get it working. The standard setup that comes with the stream deck software does definitely not work for me.

There’s a command line utility called “brightness” which is something you can call from automation tools, though it does not appear to support increments, only absolute values. Still, it may prove useful.

Note it is available via HomeBrew but a long time ago when I installed it that way it did not work, so I installed it manually from that GitHub repo.
