How to implement aws streaming transcription in react app

I was trying to implement streaming transcription in react app following this repo of aws https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javascriptv3/example_code/cross-services/transcribe-streaming-app The repo app is working correctly but when I used this same code into my react app it gives me error Like below:

Error creating microphone stream: TypeError: microphone_stream__WEBPACK_IMPORTED_MODULE_0___default(...).default is not a constructor at createMicrophoneStream (transcribeClient.js:64:1) at Module.startRecording (transcribeClient.js:30:1)
