Dock

Electron possui API's para configurar ícones de aplicativos no dock do macOS. A macOS-only API exists to create a custom dock menu, but Electron also uses the app dock icon as the entry point for cross-platform features like recent documents and application progress.

O dock customizado é frequentemente usado para adicionar atalhos para tarefas as quais o usuário não irá querer abrir totalmente a janela do aplicativo para acessá-la.

To set your custom dock menu, you need to use the app.dock.setMenu API, which is only available on macOS.
