How to imbed a video from URL?

Have you reviewed Embeds?

yes I read it. But I want to embed a video from a site that is not listed in that post.

Did you review “Adding Support For A Non-oEmbed Site”?

now I did but I didn’t understand it much.

I mean I’m pretty new to this.

I saw the https://codex.www.ads-software.com/Function_Reference/wp_embed_register_handler

The sample code for the forbes site looks difficult. How would it look for this website and this specific url: URL ?

and should this code be pasted in the functions.php file in the theme I’m using right now?
