I've seen this article;

Basically, Google Docs will support previews for Figma, Miro files and more. They call this feature "Smart Chips".
I think Confluence could develop this kind of integration further, like it does when linking a Google Drive video, but for other collaboration platforms.
For our team, it would mean that we can work even more on Confluence as we would be able to pull live previews from other platforms. Figma designs, Github roadmaps, you name it. It adds so much value.
