[Bug]: Signal-desktop does not appear in application menu, cannot create taskbar shortcut

What happened?

After installing signal using the snapcrafters snap image, I searched the application launcher for signal and could not find it. I could launch it from the Discover app. Launching it from the discover app did make it show up with an icon on the taskbar (icons only task manager), but the option to pin signal to the taskbar was
greyed out. Creating a shortcut to the application directly at /var/lib/snapd/snap/signal-desktop/673/opt/Signal/signal-desktop is possible but leaves the shortcut with no icon and launching this way does not preserve the configuration/login when launched via snap.

I am running fedora 40 kde.

What should have happened?

Ideally the application should show up in the applications list after being installed and when running, it should be possible to pin to desktop.

  **Minimize to tray**

  Per the request of the Signal developers, this snap does not use the system tray by default. This
  is disabled by default per the request of the Signal developers, because system tray support is
  not stable. Set to `false`, Signal will stop when you close it and will not have a system tray
  icon. You can enable it by running the following command.

      snap set signal-desktop tray-icon=true
