You need to add the StartupWMClass
to the .desktop
file of the launcher of the AppImage. otherwise your running instance will not get associated with the .desktop launcher and Add to Favourites option will not be there.
for example ~/.local/share/application/inkscape.desktop
file should look like
[Desktop Entry]
Name=Inkscape
Exec=/opt/inkscape/Inkscape.AppImage
Icon=/opt/inkscape/inkscape-logo.svg
Comment=Draw Freely
Type=Application
Terminal=false
Encoding=UTF-8
Categories=Utility;
StartupNotify=true
StartupWMClass=org.inkscape.Inkscape
To find the StartupWMClass entry of your application use
- for wayland use looking-glass
- for xorg run
xprop | grep WM_CLASS
in terminal and click on your application's window
