Hi! I’m developing an AI companion app and I’m stuck. My hardware only supports **Unity 2022.3 LTS**.

​The current SDK gives me **33 compilation errors** because of [UxmlElement] (which is Unity 2023+ only). I need a download link for a **Legacy version of the Unity SDK** that works with 2022.

​Please help, I really want to use Convai for my project Nivanix!
