This parameter is relevant only if your app uses the audio medium for discovery.
When set to YES, Nearby will set the AVAudioSession category and options to the values that work best for Nearby: AVAudioSessionCategoryPlayAndRecord and AVAudioSessionCategoryOptionDefaultToSpeaker, respectively. If you set it to NO, the current category and options will be preserved and used by Nearby. This may result in the inability for Nearby to broadcast or record audio. For example, if your app uses AVAudioSessionCategoryAmbient, Nearby may not be able to listen to audio from nearby devices. If your app uses AVAudioSessionCategoryRecord, Nearby will not be able to broadcast audio to nearby devices. Default is YES.
