		import { name as appName } from "../app.json";
		import RCTVideoManager from 'react-native-video/dom/RCTVideoManager'; // Add this

		// Path to RN Bundle Entrypoint ================================================
		const rnBundlePath = "./entry.bundle?platform=dom&dev=true";

		// React Native DOM Runtime Options =============================================
		const ReactNativeDomOptions = {
		enableHotReload: false,
		nativeModules: [RCTVideoManager] // Add this
		};
