Icon for launcher of appimage packet

[Paul74]

Hello,


I have several appimage packet installed and working fine.
I put launchers on desktop, launcher is correctly starting the designed app.
But, all launcher use the same "wheel" icon.


If I want to change these icons, I can't,  as clicking on "properties" doesn't provide the panel to do that.
Using right clik button doesn't provide entry "launcher edit".


May be I forgot something....


Thank in advance for yours ideas and solutions.
