 You can also provide the URL and token via environment variables:

 **End-to-End Encryption (E2EE)**
 You can enable E2E encryption for the streams via --enable_e2ee and --e2ee_key flags,
 by running the following cmds in two terminals or computers. **Note, jwt_token needs to be different identity**
 ```bash
-./build/examples/SimpleRoom --url $URL --token <jwt-token> --enable_e2ee --e2ee_key="your_key"
