In all of the iOS 13 betas so far, I have been unable to read or write the states of any HomeKit devices in a Siri Extension. I am able to create the HMHomeManager, and I receive the normal `homeManagerDidUpdateHomes()` callback that list all of my accessories normally, but interacting with them at all gives me an HMErrorCode 80, "Missing entitlement for API."
To be clear, this does work in iOS 12, and I am aware that HomeKit accessories cannot be controlled when the app is in the background. This issue is related to running in a Siri Extension, which is invoked by a users' command, but does not grant access to interact with accessories in the same way as previous versions of the OS.
