I noticed that if I add a link to a group, it appears in the post as the name of the site and not the group itself.
For example, here’s a link to a group on my site called “Team” https://hub.youthpowercoalition.org/g/team.
The link renders as the name of my site: https://hub.youthpowercoalition.org/g/team
I think it makes more sense for the link to appear as something more like: “Team Group” or “Team Group - Youth Power Hub” if on another Discourse site.
