You could use file reader to extract data from blob, for example

var blob = new Blob(["Hello", "World!"]);

const buffer = await new Promise(resolve => {
  const fileReader = new FileReader();
  fileReader.addEventListener("loadend", () => resolve(fileReader.result));
  fileReader.readAsArrayBuffer(blob);
})
