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="">
	<meta property="og:title" content="Nextcloud 22 introduction and overview">
	<meta property="og:image" content="">
	<meta property="og:image:width" content="480">
	<meta property="og:image:height" content="360">
	<meta property="og:description" content="Nextcloud 22 introduces a wide range of features. In this video we go over what&#39;s new, show it in action and hear from a few customers about their experience...">
	<meta property="al:ios:app_store_id" content="544007664">
	<meta property="al:ios:app_name" content="YouTube">
	<meta property="al:ios:url" content=";feature=applinks">
	<meta property="al:android:url" content=";feature=applinks">
	<meta property="al:web:url" content=";feature=applinks">
	<meta property="og:type" content="video.other">
	<meta property="og:video:url" content="">
	<meta property="og:video:secure_url" content="">
	<meta property="og:video:type" content="text/html">
	<meta property="og:video:width" content="1280">
	<meta property="og:video:height" content="720">
	<meta property="al:android:app_name" content="YouTube">
	<meta property="al:android:package" content="">
	<meta property="og:video:tag" content="Nextcloud">
	<meta property="og:video:tag" content="privacy">
	<meta property="og:video:tag" content="digital sovereignty">
	<meta property="fb:app_id" content="87741124305">

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.
