Updating themed icons

I use themed icons and the colour is based off of the wallpaper. However, when I use this app (which is great btw!), the icons do not update when changing between light and dark mode. Would it be possible to somehow also trigger the icons to update? When I first installed this app and applied my new wallpapers (using the same current one for light and a new one for dark mode), the themed icons all updated to match the dark mode wallpaper. My theory is that somewhere the OS presumed the dark mode wallpaper was the new sole wallpaper and matched that one instead. So there does seem to be some mechanism within the OS that, when using icons based off of the wallpaper, updates the icons when changing the wallpaper. So perhaps it's possible to notify the part of the OS handling the icons when switching wallpapers? Would be cool. Thanks for the great work! Dylan
