Rich links In Nextcloud

Nextcloud version: 22.1.0

Hello, when sharing for example Videos with links, I wanted to be able to create a rich preview, where an application like WhatsApp, Discord etc. would be able to display the video without having the need to open the link.

This is an example, of what I want to achieve. Here you could play the Video within the Application.

This is what it looks like now, when you share a Video via the link.

These Rich Links are embedded in the HTML with a meta tag with the attribute property.

Here is an example of how YouTube does it:

    <meta property="og:site_name" content="YouTube">
	<meta property="og:url" content="https://www.youtube.com/watch?v=zJ-NYGLMLxs">
	<meta property="og:title" content="Nextcloud 22 introduction and overview">

Can someone help me and tell me where I am able to change that myself.

Try adding /preview to the end of your shared url and see if it renders the video.

When adding /preview it just returns nothing.
