Retrieving Make, Model, and Device Type Details in Matter App Development using Google Home Sample App (GHA)

Question

I am new to Matter app development and seeking assistance. I am trying to retrieve details such as Make, Model, and device type for a Matter device. While exploring the Google Home sample app (GHA), I could only find deviceType, vendorId, and productId. Is there a method to obtain the additional information I need?

override fun onCommissioningRequested(metadata: CommissioningRequestMetadata) {
  Timber.d(
    "*** onCommissioningRequested ***:\n" +
        "\tdeviceDescriptor: " +
        "deviceType [${metadata.deviceDescriptor.deviceType}] " +
        "vendorId [${metadata.deviceDescriptor.vendorId}] " +
        "productId [${metadata.deviceDescriptor.productId}]\n" +
        "\tnetworkLocation: " +
        "IP address toString() [${metadata.networkLocation.ipAddress}] " +
        "IP address hostAddress [${metadata.networkLocation.ipAddress.hostAddress}] " +
        "port [${metadata.networkLocation.port}]\n" +
        "\tpassCode [${metadata.passcode}]")

}

You can retrieve details such as make, model and device type for a Matter device by enrolling yourself to the developer preview of the Google Home API. You can refer to the latest Google IO video tutorial in this regard to get an idea of the capabilities that are being now supported to make developer's interaction with matter devices smoother.
