Notification bar icons not syncing with launcher's built-in icon pack

When using Niagara Launcher's built-in icon pack, the icons on the home screen update correctly, but the notification bar still displays the original app icons instead of the ones from the selected icon pack.

Steps to reproduce:

Open Niagara Launcher settings

Apply the built-in icon pack

Check the home screen — icons are updated correctly

Pull down the notification shade — icons still show the original app icons

Expected behavior:

Notification bar icons should reflect the icon pack applied in Niagara Launcher.

Actual behavior:

Notification bar continues to display the default/original app icons after applying the built-in icon pack.

Note: Wallpaper has already been changed and is displaying correctly. Only the notification icons are out

of sync.
