AppImage for Linux isn't showing Bitwarden icon

I’d prefer using a .deb but it doesn’t update.

Is there a way to get the Bitwarden icon onto the AppImage that appears in GNOME tray?

I use Fedora and the app icon with the AppImage version of Bitwarden appears fine.

With the current Bitwarden-2024.7.1-x86_64.AppImage on Fedora 40 Workstation edition I get the standard placeholder icon (the cogwheel).

I download to ~/.local/bin, open the appimage with the Files (Nautilus) app. It opens as it should but opens the standard placeholder icon to the dock.

If you get the Bitwarden icon what am I doing wrong?
