Like UsbChooserContext this should also store the human-readable device name so
that it can be displayed in the UI that lets users audit and revoke permissions.

Also, are you sure that device_id is persistent across restarts?

Done
I did some testing to power on/off the bluetooth devices and the device_id
doesn't change.
