I am trying to load a geoserver wms layer to a WMSLayer using Esri JS API 4.x, thought the code below loads ok using Esri JS API 3.x

require(["esri/layers/WMSLayer","esri/layers/WMSLayerInfo"],function(WMSLayer,WMSLayerInfo){
    var wmsinfo = new WMSLayerInfo();

    var resourceInfo = {
        extent: Map.extent,
        layerInfos: [wmsinfo],
        spatialReference: {
          wkid: 4326
        }
    };
    var name = "HTM:name_of_layer_on_geoserver.tif";
    var url = "www.geoserver.local:8080/geoserver/HTM/wms?";
    layer = new WMSLayer(url, {
        id: "tempid",
        
        spatialReference: new SpatialReference({ wkid: 3857 }),
        resourceInfo: resourceInfo,
        visibleLayers: name,
        customLayerParameters: {CRS: 'EPSG:3857'}
    });

    Map.addLayer(layer);
});

now im trying to convert it.

require(["esri/layers/WMSLayer"],function(WMSLayer){
    //var wmsinfo = new WMSLayerInfo(); //<-this is deprecated, what would be the equivalent.

    var resourceInfo = {
        extent: View.extent,
        layerInfos: [],
        spatialReference: {
          wkid: 4326
        }
    };
    var name = "HTM:name_of_layer_on_geoserver.tif";
    var url = "www.geoserver.local:8080/geoserver/HTM/wms?";
    //moved url to properties, instead of inline argument 
    layer = new WMSLayer({
        id: "tempid",
        url:url,
        spatialReference: new SpatialReference({ wkid: 3857 }),
        resourceInfo: resourceInfo, //this doesnt seem to be available
        visibleLayers: name,   
        customLayerParameters: {CRS: 'EPSG:3857'}
    });
        layer.load().then(()=>{
      Map.addLayer(layer);
        });
});

i tried replacing visiblelayer property with sublayer but doesnt seem to work.
if i just add it to Map without the load(), it will be white screen, if i do call load(), it will stuck in getcapabilities request. i where lost that a specific class doesnt have equivalent or samples that will load a single layer rather than the all layers available in the server.

what am i missing?
