Execute script when dock is attached

Hi there,

I am currently using my ThinkPad toghether with an Thunderbolt-3 Dock from HP. A 4k Monitor, Keyboard & Mouse are connected to the Monitor.
As the internal screen has a 1080p resolution, I have to tweak some gnome settings so that I can use the external display without reaching for a magnifying glass. The scripts are ready and working - I now want to execute them whenever the dock is connected.

Currently I am trying to do this via an udev rule. But it does not seem to work... It's the first time I am writing udev rules so please be gentle ;)

The udev event I am looking for:

UDEV  [4587.334453] remove
/devices/pci0000:00/0000:00:1d.0/0000:06:00.0/0000:07:04.0/0000:3d:00.0/0000:3e:00.0/0     000:3f:00.0/usb3/3-2/32:1.0/sound/card1/controlC1(sound)

My udev rule - not working:

ACTION=="remove", SUBSYSTEM=="sound", ENV{ID_MODEL}=="HP_Dock_Audio", RUN+="/home/xvzf/bin/setup_laptopmode.sh"

ACTION=="add", SUBSYSTEM=="sound", ENV{ID_MODEL}=="HP_Dock_Audio", RUN+="/home/xvzf/bin/setup_deskwork.sh"

Greetings,
Matthias
