How to use GeoServer hosted maps within Cesium for Unreal

I have a local GeoServer serving the map imagery that I need to use in Unreal. How do I tell Cesium for Unreal that I want to use GeoServer instead of Cesium Ion? I get the sense that I need a CesiumTileMapServiceRasterOverlay component on a Cesium3DTileset actor. But what URL do I use and how exactly do I configure it?

With Geoserver, CesiumWebMapServiceRasterOverlay is the best component to use. You just need to set the URL to the base WMS service URL (it often ends in /ows or /wms) and set the Layers parameter to the WMS layer of interest.
