From what I can see, this app doesn't show a "What's New" page button in its About dialog. LibAdwaita offers convenience functions for this, to show the app's release notes.
- The new_from_appdata function, which populates large parts of the about dialog (including the What's New section) for "free" and ensures that it stays up to date over time.
- Or, manually with the release-notes property
If that can be useful as examples of implementations and how it behaves in practice, apps I found that already implement this include: stable releases of GNOME Calendar, Shortwave, Showtime, Papers, GNOME System Monitor, Decibels, Warp, etc.
