✓ Created: /home/laert/.local/share/applications/ideasy-gui.desktop
ℹ Launch from: Application Menu or Launcher
✓ Created: /home/laert//ideasy-gui.desktop
ℹ Launch from: Desktop

✓ IDEasy GUI shortcuts ready!

Usage:
  • Open your Application Menu and search for 'IDEasy GUI'
  • Or double-click the shortcut on your Desktop
  • First launch may take longer as Maven downloads dependencies

 laert@arch  ~/projects/IDEasy_1917/workspaces/main/IDEasy/gui/scripts/linux   feature/1917-create-desktop-shortcut ±  /./home/laert/ideasy-gui.desktop

/./home/laert/ideasy-gui.desktop: line 5: IDEasy: command not found
/./home/laert/ideasy-gui.desktop: line 9: IDE: command not found

The script works and the shortcut does appear in the Application Menu, but I cannot seem to open it either from the Launcher or by using the script in the home directory itself.
