[CattoFace]

OS: Manjaro on kernel 6.4.14-1-Manjaro 64 bit
Linux Desktop Manager: KDE 5.27.7 QT 5.15.10 on X11
Birdtray version: 1.11.4
Thunderbird version: 115.2.2
Birdtray origin: from the AUR, package birdtray-1.11.4-1
Qt version: NA

Description
The tray icon and desktop icons for bird tray are the old icons

Expected behavior
Both icons using the updated thunderbird icons

To Reproduce

1. install birdtray from the AUR

Screenshots

Additional context
I attempted to reinstall birdtray and the issue persisted, but I noticed another bug report had the updated icon so I am not sure why its wrong for me as I am using the latest version(except git)
I also attempted to reset the icon in the settings and it didnt fix the issue.

I believe that Birdtray uses its own icon by default. You can change the tray icon in the app's settings. To change the desktop icon to anything else, you must edit the desktop file.
