v4.0.6 GDK Support and UI Fixes

Various UI bug fixes and better support for controller navigation. The UI code now better supports Addressable implementations of the Browser as well.
The plugin (including the UI) is now supported on Xbox GDK. However, due to the GDK being exclusive to approved developers please contact us directly for the additional files required to fully support an Xbox GameCore build. You can speak to a team member on our discord server: https://discord.gg/nm46CNz88e

Note: It is recommended when using the .unitypackage file to update the plugin, completely remove the plugin first.
