Appimagelauncher wrong/missing icons

Appimagelauncher (recommended on the logseq site to launch its appimage) has 2 issues with icons I’ve encountered:

  1. Taskbar uses electron icon:
  2. Add new graph window is using default xorg icon:

In case anyone needs it, I was able to fix both for myself on KDE (might be a better way, but that’s what I’ve done).
Taskbar icon fix: right click on app launcher → edit applications → change icon
Graph Window: right click on the title bar → More actions → Configure Special Window Settings → Add Property → Desktop file name → set path to a desktop icon (use e.g. this if you don’t have it: Linux .desktop file · Issue #4728 · logseq/logseq · GitHub)
