Slack previews

We have the GitLab app added to slack. I would have expected that once added, sharing a URL to an Issue would show some kind of preview of the issue in the channel. I can’t seem to find any sort of configuration about doing so or how to make it possible. Does anybody have any clues on how to get previews of issues in slack?

Same here. We are paying for the self-hosted version, developer here, not admin. Is there a switch I can ask them to toggle, or is slack integration for gitlab hosted gitlab only?
