How to automatically make "full screen" in the browser's video player?

Question

JavaScript

There are websites where I watch TV.
Standard browsing procedure:
1) open the url
2) click the player's start button
3) click the player's "full screen" button

example site - Singapore TV, channelnewsasia .com/news/livetv

can these three actions be automated into one? maybe you can, for example, write javascript and drive it into the browser using, for example, greasemonkey? Or does anyone know a ready-made solution?

Autorun can be organized like this, but something didn’t work with fullscreen :(
you can play around with the delay value (now 5000ms = 5 seconds)

// ==UserScript==
// @name         New Userscript
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  autostart player!
// @author       You
// @match        https://www.channelnewsasia.com/news/livetv
// @grant        none
// ==/UserScript==

(function() {
    'use strict';
    // Your code here...
setTimeout(() => { window.document.querySelector(".oo-state-screen-selectable").click(); }, 5000);
})();
