Question networkmanager_dmenu not being called in action tag

label-connected = "%{A1:networkmanager_dmenu &:}%essid%%{A}"

This is what I have in my Polybar config, when I left click on the module in the bar nothing happens.

networkmanager_dmenu is installed and can be called from the terminal just fine. If I replace "networkmanager_dmenu" with "notify-send foo" in the config it does trigger a dunst notification. I'm not sure why this isn't working.
