Desktop application icon

Hi,

I need to create a desktop application icon so that the application launches from the clear linux desktop.
Is there a way to do this?

We are using a touchscreen monitor.

Thanks,
Pedro

This could work.

Edit: Alright did a little reading and you could get a problem trying to install a gnome-extension via Firefox. Check this thread for help with that (user confirms it works with chromium-based browsers).
