Invalid Menu on Linux

[MarcKarasek]

I am trying to create a new menu for a new window.
Tried the fix from #47, did not work
If I remove the menu from the new window (not main window) then it works and I see the menu from the Main window in the new window.

error-utils.ts:14 Uncaught Error: Could not call remote method 'open'. Check that the method signature is correct. Underlying error: Invalid Menu
Underlying stack: TypeError: Invalid Menu

windowManager.templates.set('read', {
'width': 800,
'height': 600,
'position': 'topLeft',
'showDevTools': false,
'resizable': true,
'title': 'Load',
'menu': {
label: 'Read',
submenu: [
{ role: 'quit' }
]
},
'webPreferences': {
// preload: path.join(__dirname, 'preload.js'),
'nodeIntegration': true
},

readwin = windowManager.createNew('readwin', 'Read eeprom', path.join('file://', __dirname, '/read.html'), 'read')

In the main window I am using Menu to set the menu

app.on('ready', () => {
const menu = Menu.buildFromTemplate(template)
Menu.setApplicationMenu(menu)
})

If I remove this and try to set this from the template 'menu': it fails in the same way when opening the main window.

in tempalte.set 'main': template

let template = [{
label: '3DXTech',
submenu: [{
label: 'Load EEPROM FIle',
accelerator: 'CmdOrCtrl-L',
click() { load_eeprom() }
}, {
label: 'Save EEPROM File',
accelerator: 'CmdOrCtrl-S',
click() { save_eeprom() }
}, {
label: "Quit",
accelerator: 'Command-Q',
role: 'quit'
},
]
}, {
label: 'Debug',
submenu:[{
label: 'Toggle Development Tools',
accelerator: 'CmdOrCtrl-D',
click: (item, focusedWindow) => {
if (focusedWindow) {
focusedWindow.toggleDevTools()
}
}
}]
}]

Got it to kinda work with Menu.buildFromTemplate(template)

But it changes both the main window and the new window..

What is the process for a new window to have it's own menu.
