Hi, The WWDC2021 Video Add support for Matter in your smart home app has a bunch of code examples referencing APIs that are no longer present or deprecated, e.g. this one. Unfortunately the documentation doesn't give any hint on the replacement APIs. Most of them are to be found in HMMatter* objects. But in the video at 14:27 an API for CHIPDeviceController is shown. Unfortunately that one cannot be found anymore. Does anybody know how to achieve the described task (managing state and control of a matter accessory)

I'm looking for a tutorial or documentation on HMMatterRequestHandler. I'm aware of the brief mentions in wwdc21-10298 but it's not sufficient. Is there any tutorial/ more extensive documentation?

I'm trying to commission a matter device via HMAccessorySetupRequest.performMatterEcosystemAccessorySetup. After scanning the QR code via the system provided UI the app shows a system popup: Additional Setup Required This accessory required additional setup. Refer to the manufacturer's guide for more information Unfortunately there's no further information. Did anybody succeed in using this API and could assist?
