Trying to remote control the KVM with an Arduino -> It's not detected in HID ports

Disclaimer ahead. This is a totally niche use case and question that I don’t expect anyone to have tried before but maybe someone can point me in the right direction.

I’m trying to figure out if there’s a way to automate operating the KVM. For really no other reason than “why not?”. I stumbled into this project here ( GitHub - jensweimann/esphome_ducky ) to turn an arduino into an HID device that can receive commands through the network and thought that I could use that to plug into one of the HID ports on the KVM and send the key combinations that trigger the different functions.

I had all the pieces laying around so quickly put it together and it works perfect!.. when connected to any of the normal USB3 ports. Gets detected as an HID keyboard and an HID mouse in the Windows device manager and I can send commands to it through MQTT.
The problem is that when I connect it to any of the white HID ports in the KVM then it seems like its not passed through to the computer? No new devices show up and of course anything I send doesn’t reach the computer.

Like I said, very niche and weird use case but, has anyone done anything even remotely like this before? Or more experienced with Arduino programming that can throw me a hint?.

Thanks!.
