I may have found a trick to display only one menu. It's by adding 2 dummy items to the array:

{
  label: null
},
{
  label: null
}

Like this:

const exampleMenuTemplate = [
	{
		label: 'Simple O&ptions',
		submenu: [
			{
				label: 'Quit',
				click: () => app.quit()
			}
		]
	},


{
  label: null
},
{
  label: null
}
]
