Connecting Homelink capable button to Home Assistant VM - hardware required?

I’ve found some multi-function buttons that I like (Onvis Switch HS2) and I’ve been trying to get it working in Home Assistant.

If I understand correctly, I can’t pull it in with the Homelink integration because its a button. I set up a ESP32 Bluetooth Proxy and my Home Assistant VM can see it now, but when I try to add it I get a timeout.

I think its timing out because it tries to configure it and hand it off to Matter, but I don’t have a physical Matter device connected to Home Assistant. I bought a second SLZB PoE adapter because that’s what I’m using for my Zigbee connectivity, but it looks like it only supports Thread over USB connection (which I’m trying to avoid).

Am I correct in thinking that the issue is because I need to have a Thread device directly connected to the Home Assistant VM? Are there any PoE alternatives similar to how the SLZB works where I can add it over the network?

Thanks for help and suggestions!
