Hello, I'm adding some screenshots of the issue (Gnome 45.1) for reference. There are two seperate dialogs currently, styled differently, that show the same information.
Also, I think that this bug ought to be labeled as a security issue. It is expected and common to receive authentication dialogs on all major operating systems (desktop, mobile), and they reference the application requiring authentication (and why, but that is a different bug).
Perhaps in the past it was less common, but omitting this info now feels unfinished.
