I have a react app where I have to download file on press of a button,Here's how my java backend is returning the file in get request:

if (Files.exists(filePath)) {
        response.setContentType(Files.probeContentType(filePath));
        response.addHeader("Content-Disposition", "attachment; filename=" + file.getName());
        Files.copy(filePath, response.getOutputStream());
        response.getOutputStream().flush();
      }

How do I read it in the react frontend and download it on button press?
