icon.ico and icon.icns generated in 'wrong' folder, while using --flatten option

[IITSTaron]

I am using the electron-icon-builder with flatten option to generate the correct icons before building an electron app with the vue-cli-plugin-electron-builder.
The problem I face here is that the icon-builder is generating the icon.ico and icon.icns files into the ./build/icons directory.

According to the electron-builder documentation (https://www.electron.build/icons), the builder is expecting the .ico and .icns files to be located in ./build, not in ./build/icons. If situated somewhere else, the .png files are used as a fallback and display quality of the app icon is clearly decreased.

Of couse this can easily be avoided by adding a manual step, which moves the two files from ./build/icons to ./build, but this could possibly be handled by the icon-builder itself.
