How can I read services with tokens published on the supermap platform in cesium for unreal?

My client now has a requirement that they use WMS services published by Supermap with tokens. After testing, I found that they cannot load and read in the CESIUM for Unreal. However, WMS services with tokens published by other platforms can be read in cesium for unreaal. How can I read services with tokens published on the supermap platform in cesium for unreal?

I’ve never used (or even heard of) Supermap, so it’s hard to say. Any messages in the Output Log?
