I added the link of a SharePoint Online file as a weblink to a Jira issue.
Jira Cloud recognizes the weblink as a SharePoint/Onedrive link and offers me the possibility to build a preview.

Is this a new build-in feature in Jira and Confluence Cloud? I did not find any articles or news regarding this opportunity.
If the preview will look great I guess that every chargeable SharePoint -Jira/Confluence integration would be redundant.
Has anyone already tried the built in connectivity?
