WebBluetooth API: How to get current device's id

I'm using WebBluetooth API in Chrome 80 with experimental flag enabled. I can retrieved all nearby devices' info with navigator.bluetooth.requestLEScan. However, when it comes to the current device that I'm making scan from, there doesn't seem to be a way to retrieve information about it. Is there anyway that I can retrieve information of the current bluetooth device?

I couldn't find anything from here, here, nor here
