HomeKit bridge can't be added to Home iOS App

I’m running HomeAssistant OS under a ProxMox virtual machine.
I’ve setted up the HomeKit integration and it’s configured to be announched as a bridge.
When I try to add the bridge to my Home app using my iPhone I get the error “Accessory not found”.

I saw on the documentation Troubleshooting section this paragraph:

Accessory does not appear in the Home App (for pairing) - Libvirt QEMU/KVM virtual machine with macvtap adapter

but I’ve no idea where to add this configuration.
Any help is appreactiated.
