WWDC 2022 announced CallKit for WatchOS 9, but didn't explain how to use it. I was able to convert SpeakerBox sample from iOS to WatchOS. The CallKit itself seems works fine, but I stuck with networking issue. I cannot understand how to stream RTP audio. I have background audio enabled. If I configure audio session for CallKit with .playAndRecord category, I cannot specify .longFormAudio policy, as it's not applicable for this category. Without .longFormAudio low lever API is denied ("Path was denied by NECP policy").

Thanks for quick response. Fortunately beta 2 is out recently and I was able to try it. The issue seems fixed! I setup .playAndRecord category as usual without specifying a policy. I can see app is able to make network requests after audio session activated.
