FaceTime screen record but there is no way to record the audio? What? That's silly!

Maybe I'm missing something, but what is the point of being able to screen record the facetime video if the audio feature is disabled? I'm on IOS27, iPhone 17 pro max and they showed the new Iphone duo with the new feature but to screen record the facetime with no audio is kind of useless? Am I missing something the purpose of this?
