Audio recorder using app designer

Hello, I am trying to bulid a audio recorder app based on the following code I wrote in a Script:

Fs = 8000;

recObj = audiorecorder;

while 1

a = input('0 to start,1 to stop,2 to pause,3 to resume');

switch a

case 0

record(recObj);

disp('started recording')

case 1

stop(recObj);

break;

case 2

pause(recObj);

case 3

resume(recObj);

end

end

audioData = getaudiodata(recObj);

filename = 'C:\Users\Lenovo\OneDrive\Desktop\MySpeech.wav';

audiowrite(filename, audioData,Fs);

disp('done recording');

But I am not able to record any audio using the app, an empty file is being saved. Can anyone please help me with this?
