How to pick a specific microphone when recording video AVCaptureSession

My app is recording video using the front camera, and I'd like to lock the audio portion to use a specific microphone.

Code Block let captureSession = AVCaptureSession()
captureSession.sessionPreset = .hd1280x720        
guard let captureDevice = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .front) else {return}        
// Get Audio Device        
guard let audioInputDevice = AVCaptureDevice.default(for: .audio) else {print("Could not get audio"); return}        
guard let videoInput = try? AVCaptureDeviceInput(device:captureDevice) else {return}
guard let audioInput = try? AVCaptureDeviceInput(device:audioInputDevice) else {return}
captureSession.addInput(videoInput)        
captureSession.addInput(audioInput)

Code Block
let captureSession = AVCaptureSession()
captureSession.sessionPreset = .hd1280x720

guard let captureDevice = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .front) else {return}

// Get Audio Device
guard let audioInputDevice = AVCaptureDevice.default(for: .audio) else {print("Could not get audio"); return}

guard let videoInput = try? AVCaptureDeviceInput(device:captureDevice) else {return}

guard let audioInput = try? AVCaptureDeviceInput(device:audioInputDevice) else {return}

captureSession.addInput(videoInput)
captureSession.addInput(audioInput)

I can set the video to the specific camera, but I haven't seen how to set the audio device to a specific microphone when using AVCaptureSession.
