App Development to control VR

I have developed a VR(Meta Quest, using Unity ) application and need to interact with it via a Smartphone App. I have developed a basic app containing WebSocket server to manage communication with Flutter but the following functionalities need to be implemented:

- Casting using WebRTC: The VR side functionality has been implemented. The App side functionality needs to be created.
- Autodiscovery and auto-connect via local network: The App and VR have to be able to connect to each other automatically without the user having to set manually the IP address.
- Security: Implement security protocols for the VR- Smartphone app interaction.
- UI and UX improvement: Basic UI is implemented but needs improvement

There will be a follow-up opportunity to improve the application upon successful implementation.
