Cesium for Unity WebGL Question

Hi there, I would like to ask how to package and publish web files in Unity using Cesium for Unity. The error is as follows:
Library\PackageCache\com.cesium.unity@1.7.1\Runtime\Cesium3DTile.cs(2,7): error CS0246: The type or namespace name ‘Reinterop’ could not be found (are you missing a using directive or an assembly reference?)
First of all I made sure the library is there, secondly I pulled it on github and put it in my project and it says that the code in the library uses c#10.0 and does not support c#9.0.
My Unity version is 2023.2.10f1. Is there any solution to this, please? Or is there an alternative strategy that allows me to package web files with cesium for unity?

Hi @xiameishicang,

Welcome to the community! As mentioned in some other forum threads, WebGL support is not available in Cesium for Unity.

If you need to use WebGL, we offer a pure WebGL rendering engine with CesiumJS that you can use for your 3D geospatial needs. Thanks!
