So I have a method

@GetMapping(
            value = "/download/{fileId}",
            produces = { MediaType.APPLICATION_OCTET_STREAM_VALUE }
    )
    public ResponseEntity<InputStreamResource> download(@Valid @PathVariable(value = "fileId") String fileId) {
        InputStreamResource file = new InputStreamResource(service.download(fileId));

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(new MediaType(MediaType.APPLICATION_OCTET_STREAM, Charset.forName("UTF-8")));
        headers.setContentDispositionFormData("attachment", fileId+".doc");
        headers.add("Content-Transfer-Encoding", "binary");

        return ResponseEntity.ok()
                .headers(headers)
                .body(file);
    }

and when I hit the API from postman, it returns : enter image description here

How can I make the output readable and downloadable from postman?
