'How to disable and re-enable menu bar

I would like to disable the menu bar (make it grey and unopenable). How to do that?

I tried the following code but it removes the menu bar instead of disabling it.

Menu.setApplicationMenu(null);

javascript electron

Currently (being Electron v18.1.0) , you can't disable top level menu items.
