Suporte para o botão no macOS

Para que os botões extra de notificações funcionem no macOS, sua aplicação deverá atender aos seguintes critérios:

• Aplicação é assinada
• App has its NSUserNotificationAlertStyle set to alert in the Info.plist.

Se nenhum desses critérios forem atendidos, o botão não irá aparecer.

Selection support on Windows

To add a selection (combo box) style action, include an action with type: 'selection', a text label for the submit button, and an items array of strings:

const { Notification, app } = require('electron')

app.whenReady().then(() => {
  const items = ['One', 'Two', 'Three']
  const n = new Notification({
    title: 'Choose an option',
    actions: [{
      type: 'selection',
      text: 'Apply',
      items
    }]
  })

  n.on('action', (e) => {
    console.log(`User triggered action at index: ${e.actionIndex}`)
    if (e.selectionIndex > 0) {
      console.log(`User chose selection item '${items[e.selectionIndex]}'`)
    }
  })

  n.show()
})

When the user activates the selection action, the notification's action event will be emitted with two parameters: actionIndex (the action's index in the actions array) and selectedIndex (the zero-based index of the chosen item, or -1 if unavailable). On non-Windows platforms selection actions are ignored.
