Commission Matter accessory added via Apple Home

Greetings!

I've added a Matter accessory via the Apple Home app. In my app, I'm attempting to commission this device and add it to my fabric. However, when I try to open the commissioning window, I receive an error stating, MTRBaseDevice doesn't support openCommissioningWindowWithDiscriminator over XPC.

It appears that opening a commissioning window via an XPC connection is not yet supported. Is there another method to commission the device? Can I retrieve the setup payload from the MTRBaseDevice object or the shared MTRDeviceController?

Here's the simplified version of my code:

var home: HMHome // HMHome received via HMHomeManager
var accessory: HMAccessory = home.accessory[0] // my Matter-supported accessory

let deviceController = MTRDeviceController.sharedController(
    withID: home.matterControllerID as NSCopying,
    xpcConnect: home.matterControllerXPCConnectBlock
)

let device = MTRBaseDevice(
    nodeID: accessory.matterNodeID as NSNumber,
    controller: deviceController
)

device.openCommissioningWindow(
    withDiscriminator: 0, 
    duration: 900, 
    queue: .main) { payload, error in
        if let payload {
             // payload not received
        } else if let error {
            // I'm getting here "Error Domain=MTRErrorDomain Code=6 "(null)""
            // and "MTRBaseDevice doesn't support openCommissioningWindowWithDiscriminator over XPC" logged in the console
            print(error)
        }
