View a file using a authentication token

I have a general question.  Is it possible using the dropbox api to view a file using an authentication token rather than logging in?

I am creating a website that uses dropbox to store documents that are not for public viewing.  I dont want to enable link sharing (which I have done successfully already for something else) but i would like them to click a file and go and view it (using an athentication token that the server provides) rather than dowloading it (which ive also figured out).  

Ive had a look through the api but cant seem to find anything that fits the bill. 

Dropbox in node (pretty sure this is the official dropbox node api)

// UPLOAD CODE (working) //

import fetch from 'isomorphic-fetch';
import {Dropbox} from 'dropbox';
import {Meteor} from 'meteor/meteor';

import {
  FILE_UPLOAD,
  FILE_UPLOAD_ERROR,
  FILE_UPLOAD_SUCCESS,
} from '../../store/reducers/file/constants';

export default async function uploadFile(file, callback, data) {
  data.dispatch({type: FILE_UPLOAD, payload: true});
  Meteor.call('authDropbox', async function(error, result) {
    try {
      const dbx = new Dropbox({accessToken: result.token, fetch: fetch});
      const response = await dbx.filesUpload({
        contents: file, 
        path: `/${data.location}/${file.name}`,
        mode: 'add',
        autorename: true,
        mute: true,
      });
      callback(response, data);
      data.dispatch({type: FILE_UPLOAD_SUCCESS});
    } catch (err) {
      data.dispatch({
        type: FILE_UPLOAD_ERROR,
        payload: err.message,
      });
    }
  });
}

// DOWNLOAD CODE (working) //

import fetch from 'isomorphic-fetch';
import {Dropbox} from 'dropbox';
import {Meteor} from 'meteor/meteor';
import {saveAs} from 'file-saver';

export default async function downloadFile(file) {
  Meteor.call('authDropbox', async function(error, result) {
    try {
      const dbx = new Dropbox({accessToken: result.token, fetch: fetch});
      const response = await dbx.filesDownload({path: file.path_display});
      saveAs(response.fileBlob, response.name);
    } catch (err) {
      console.log(err);
    }
  });
}

// CREATE SHARING LINK (working) //

//this should be inserted in the upload code while authorised
const response = await dbx.sharingCreateSharedLink({
    path: `/${data.location}/${file.name}`
});
const sharingLink = response.url;  
//store sharing link somewhere i generaly do it in the callback
