This Repository only for Oculus Quest 2

This is a project I created for Oculus Quest 2, using the MRTK, but it does not work with HoloLens. This is because the WebView used is an Oculus (or Android) dependent system.

Requirements

• Unity 2021.3 LTS
• Mixed Reality Toolkit
• Oculus Integration
• TLabVKeyborad
• TLabWebView
