How to setup a Parse Server that uses Spaces CDN?

I just setup my first Space, connected my Parse Server to it and everything works, but I’m not sure I have enabled anything CDN-wise, or if I have to.

I’m using the configuration below

var express = require('express');
var ParseServer = require('parse-server').ParseServer;
var path = require('path');
var S3Adapter = require('parse-server').S3Adapter;
var AWS = require("aws-sdk");

var databaseUri = process.env.DATABASE_URI || process.env.MONGODB_URI;

//Set Digital Ocean Spaces EndPoint
const spacesEndpoint = new AWS.Endpoint('https://fra1.digitaloceanspaces.com');
//Define S3 options
var s3Options = {
  bucket: 'bucket',
  baseUrl: 'https://bucket.fra1.digitaloceanspaces.com',
  region: 'fra1',
  directAccess: true,
  globalCacheControl: "public, max-age=31536000",
  s3overrides: {
    accessKeyId: 'accessKeyId',
    secretAccessKey: 'secretAccessKey',
    endpoint: spacesEndpoint
  }
};

var s3Adapter = new S3Adapter(s3Options);

var api = new ParseServer({
  publicServerURL: 'http://ip:1338/parse',
  filesAdapter: s3Adapter
});

Any thoughts will be much appreciated!
