Hi, I tried to load this demo: https://mdbootstrap.com/previews/docs/latest/html/navigation/side-nav-hidden-navbar-fixed.html# which is what I need, but it appears that it doesn't work:When I click on the hamburger menu, nothing happens. I checked the console and I get this: GET https://mdbootstrap.com/previews/docs/latest/js/jquery-3.3.1.min.js 404 (Not Found)bootstrap.min.js:6 Uncaught TypeError: Cannot read property 'fn' of undefinedat bootstrap.min.js:6at bootstrap.min.js:6at bootstrap.min.js:6at bootstrap.min.js:6(anonymous) @ bootstrap.min.js:6(anonymous) @ bootstrap.min.js:6(anonymous) @ bootstrap.min.js:6(anonymous) @ bootstrap.min.js:6mdb.min.js:1 Uncaught ReferenceError: jQuery is not definedat mdb.min.js:1(anonymous) @ mdb.min.js:1side-nav-hidden-navbar-fixed.html:180 Uncaught ReferenceError: $ is not definedat side-nav-hidden-navbar-fixed.html:180
