How can UE load the TMS service published by Geoserver

I am using the tms service published by geoserver. Figure 1 and Figure 2 are his sliced data. The /tilemapresource.xml you mentioned does not exist. Figure 3 is his request method and return content (can be loaded using cesium js), The xml structure he returns is consistent with the tilemapresource.xml produced by cesiumlab
