		width: 900,
		height: 900,
		webPreferences: {
			partition: "persist:test",

	});
	electron.session.fromPartition("persist:test").protocol.registerFileProtocol("test", function (request, callback) {
		let finalUrl = path.join(electron.app.getAppPath(), "/test.html");
		finalUrl = path.normalize(finalUrl);
		callback(finalUrl);
	});

	browserWindow1.webContents.loadURL("https://example.com");

electron.app.on("ready", () => {
