I have been searching with no luck, where can I find documentation for the system tray icons?

I am aware that now in Plasma 6 they come from the Icon theme, but how are they mapped? How do I know which file each tray entry is looking for on my Icon theme? What about cases like volume, Bluetooth, network... we use to have a single file for each that contained the different -states- they could be.

I tried just dropping my plasma theme icons on my Icon theme and got some weird results, for instance Bluetooth now shows the network icon, some other icons did not change at all.

How does it work? I mean I have several Containments numbers like: [Containments][8] ... [Containments][23] ... I get that some are for the background of plasma where the wallpaper goes, some are for panels

But overtime it seems it gets messy, with repeated background ones and panels.

I guess I want to know how plasma interprets it, whats the logic for these IDs and why as I change my plasma settings the amount of containers increase even if I don't add more panels, screens etc.

When we go to Konsole main menu » Settings » Toolbars Shown and check or uncheck any option, where does it get stored?

I checked ~/.config/konsolerc and it was not stored there.

I actually toggled them and checked all files in my system that were changed at the same time I toggled them and I still could not find.

My ~/.local/share/kxmlgui5/konsole/ has no files in it, both on Arch and Void Linux. I also tried creating a partui.rc file as well as konsoleui.rc to see if it would get populated when changing which toolbars are shown and which aren't but it did not work. My KDE Version is 5.27.10 on both distros.
