• Electron-Builder Version: 22.11.7

• Node Version: 16.6.2

• Electron Version: 13.1.9
• Electron Type (current, beta, nightly): current

• Target: linux

According to here https://www.electron.build/generated/platformspecificbuildoptions

• icon String - The path to icon (.icns for MacOS and .ico for Windows), relative to build (build resources directory). Defaults to ${firstExt}.icns/${firstExt}.ico (if several extensions specified, first is used) or to application icon.

Not supported on Linux, file issue if need (default icon will be x-office-document).

We are building an app also for linux. After the install the file association action is working fine (double click will launch the app), but in file manager, the icon for the project file is shown as x-office-document

I see in the /usr/share/mime/applications, the association is set as

WebLogic Kubernetes Toolkit project file

Is there a way, you can support the icon field on linux - showing the icon provided instead of x-office-document
