From this fetch. Not WhatsApp’s preview.
WhatsApp preview
Meta’s WhatsApp link preview guide lists og:title, og:description, og:url, and og:image, within the first 300 KB of the page’s HTML. The image should be an absolute URL, under 600 KB, at least 300 px wide, and no wider than 4:1. Without these tags, WhatsApp may try other mark-up, but Meta says not to rely on that.
WhatsApp keeps a preview it has already fetched. This check reads the live page. It does not clear that cache. WhatsApp and Telegram link preview
