Changing the default icon in Netbeans Native Deployment for Java Applications

I know the question is very long, but in a nutshell it is. As you know, Netbeans has a feature through the inno setting that allows you to create .exe installers of Java applications. The problem is, I would like to change the default icon it has (gray java icon) to a custom one.

I've searched both Stack and Google many times and I haven't found anything. The closest thing he got was to modify it via Launch4j. The point is that it is possible to do this in Netbeans.

Also, I was wondering if there is an option to add multiple languages ​​to the installer and some other functionality such as creating a desktop icon. I think if the option exists, it will be in the same place as the change icon ... but I completely lost this problem.
