When I paste links from our company Confluence Data Center site (uses SSO) into Microsoft Teams or Slack, there's no nice link preview ("unfurl" in Slack terms) with a page title and description. I spent a couple of hours figuring out how to add Facebook's commonly used "og" meta tags to the Velocity template, but the link previews don't work. I finally realized this is probably due to authentication: Teams/Slack cannot fetch the content without some credentials, either mine or something baked into Teams.
Is there some clever way around this? BTW if it helps anyone, here's code I added to the Main Layout in Confluence. I did not find, frankly, any useful docs on how to reference specific properties and did a lot of trial and error. The URL bit isn't right but I'm stuck anyway ...
