        width: 800,
        height: 600,
        autoHideMenuBar: true,
        show: false,
        // frame: false // -> now work, you can remove the frame properly !!
    });

    win.setDarkTheme();
    win.setMicaEffect();

    // win.alwaysFocused(true); // -> allows you to keep the mica effects even if the window is no focus (decrease performance)

    win.loadFile(path.join(__dirname, 'files', 'index.html'));

    win.webContents.once('dom-ready', () => {
        win.show();
    });
