Icon change (Mosaic, Mosaic editor, Scheduler, Trend log)

[fleeceable]

I was able to change shortcut icon what goes to home screen but was unable to change these icons what is in LM UI or LM Home app UI.
Can you please provide me path address for example schedulers?

When trying
/apps/data/schedulers/icon.png
/apps/core/e.schedulers/icon.png

I don't get any response when logging io.writefile().
