‌Requirement:‌ The solution must not rely on any form of HTTP server. The dist bundle must run Cesium maps when double-clicking index.html on any computer. This is because the dist needs to be integrated into ‌Unreal Engine 5 (UE5)‌ for interaction with UE5. However, UE5 can only load index.html that opens directly via double-clicking.

‌Problem:‌ Double-clicking index.html fails due to CORS errors or compatibility issues. Alternatively, if there are UE5 experts, how can an index.html (which cannot run via double-clicking) be deployed within UE5 for interaction?
