Use the embed option and link to your swf file. Here is some embed code to put into it. I also use this on WIX. It now plays AS2 great. The code auto plays.
<script>
window.RufflePlayer = window.RufflePlayer || {};
window.RufflePlayer.config = {
"autoplay": "on","splashScreen": false,"unmuteOverlay": "hidden"
};
window.addEventListener("load", (event) => {
const ruffle = window.RufflePlayer.newest();
const player = ruffle.createPlayer();
const container = document.getElementById("container");
container.appendChild(player);
player.load("https://example.com/Your-Movie.swf");
player.style.width = "700px";
player.style.height = "400px";
});
</script>
<script src="https://unpkg.com/@ruffle-rs/ruffle"></script>
<div id="container"></div>
