Audio input is not working on iOS Unreal app

I am packaging my Unreal app for iOS which has Metahuman and Inworld AI sdk integrated.
In my app I can give voice commands to the Metahuman and get response using Inworld AI. It works fine on my Mac and Android device but when I try to use the same for iOS its not working.

The audio input/ audio capture is not working in iOS app, evenif the Microphone permission is granted within the app. I have also implemented audio capture component in Unreal but same issue is there that Microphone is not taking input, even if the Microphone permission is granted
I’m stuck with it and not finding way around.

Could anyone please help with this issue?
