I want to write ByteArray data which is coming from Retrofit API(ResponseBody as return type from API) into Excel file and store into Internal Memory of android SD Card

try {

var path = mContext?. getExternalFilesDir(Environment.DIRECTORY_PICTURES)

    val stream = FileOutputStream(path.toString()+"/ExcelTest.xls")
    stream.write(it.data?.bytes())//it.data->retrofit ResponseBody that am convert to ByteArray
    stream.flush()
    stream.close()


//To open the Excel file
  val intent = Intent(Intent.ACTION_VIEW).apply {
      setDataAndType(Uri.fromFile(path), "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
      flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
  }
  mContext?.startActivity(intent)
} catch (e: FileNotFoundException) {
    
}

Below is my Suspend Method:
  @GET("URL")
  @Streaming
suspend fun getDownloadFile():ResponseBody
