I am having trouble setting up #pipewire to limit my microphones volume.

Below is the #wireplumber configuration.
# START
# For "Dell Inc. Latitude 5290 2-in-1"
# The analog input array is way too loud

monitor.alsa.rules = [
{
matches = [
# This matches the value of the 'node.name' property of the node.
{
node.name = "alsa_input.pci-0000_00_1f.3.analog-stereo"
}
]
actions = {
update-props = {
node.description = "Dell Latitude 5290 2-in-1 Stereo Microphone"
channelmix.min-volume = 0.0
channelmix.max-volume = 0.25
channelmix.normalize = true
}
}
}
]
# END

What am I doing wrong? (I know the node match is working btw)
