AudioCapture is not implemented on IOS?

Tell me the AudioCapture component is not implemented on IOS? The test project with AudioCapture at my level works fine on Windows, Android, iMac, but not on IOS. In plist I have added the string:

<key>NSMicrophoneUsageDescription</key><string>bla bla</string>

in the settings of the AudioCapture component, it is “AutoActivate” and when playing the game, I hear my voice when I say something, but not on IOS. Please tell if there is any way to make AudioCapture work on IOS, possibly via C++?
