Used to we put link and its previewed now it's not accepting even scripts of embed video.
Any solution?

iframe codes and embed codes not works. It's counting 1 space like five or more gap.
So if you don't want injection of codes.
Maybe you can add YT or Video plugin into HTML editor.
Examples I tried so far.

<div> https://www.youtube.com/ULZ0s7AOCOA   <iframe width="560" height="315" src="https://www.youtube.com/embed/ULZ0s7AOCOA?si=4Pi_4akQ22tp25v6" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>

var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '360',
width: '640',
videoId: 'ULZ0s7AOCOA',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}

<iframe id="player" type="text/html" width="640" height="360" src="https://www.youtube.com/ULZ0s7AOCOA" frameborder="0"></iframe> </div> https://developers.google.com/youtube/iframe_api_reference?hl=fr

When i check ICU page source is like this...
<span data-s9e-mediaembed="youtube" style="display:inline-block;width:100%;max-width:640px"><span style="display:block;overflow:hidden;position:relative;padding-bottom:56.25%"><iframe allowfullscreen="" loading="lazy" scrolling="no" style="background:url(https://i.ytimg.com/vi/uxnmbEt5Qqg/hqdefault.jpg) 50% 50% / cover;border:0;height:100%;left:0;position:absolute;width:100%" src="https://www.youtube.com/embed/uxnmbEt5Qqg"></iframe></span></span>
