I want to use an online terrain server instead of Cesium Ion to load terrain data organized in quantized-mesh-1.0 format, which needs providing a token parameter in its url. URL is like https://my.terrainserver.com/terrain/{z}/{x}/{y}.terrain?v=1.0&token=myToken.
It seems that I can use CesiumTerrainProvider.fromUrl to load terrain data correctly, but the requests always miss the token parameter and get a status code of 401 tells me that “no token or authorization”.
How can I add a token parameter in that request?
