两个方法绘制了两个图标点，位置相同，其中一个遮住了另一个

问题遇到的现象和发生背景

想让下面被遮挡的那个点显示在上面，有没有方法能设置一下他的优先显示层级

第一个点
var entitie = this.$viewer.entities.add({
        name: "point",
        id: "point",
        position: position,
        billboard: {
          image: `${process.env.BASE_URL}imgs/xiauq.png`,
          scale: 0.7,
          horizontalOrigin: Cesium.HorizontalOrigin.CENTER,
          verticalOrigin: Cesium.VerticalOrigin.BOTTOM,
          heightReference: Cesium.HeightReference.CLAMP_TO_GROUND,
          clampToGround: true,
          pixelOffset: new Cesium.Cartesian2(5, 10),
        },
      });

第二个点
if (wkt.indexOf("POINT") != -1) {
          let point = wkt.split("POINT(")[1].split(")")[0].split(" ");
          flyPoint = point;
          // 回显
          let loadjsonEntitles = [];
          let showGeojson = {
            type: "FeatureCollection",
            features: [],
          };
          let lnglat5 = [];
          lnglat5.push(point);
          let Feature = {
            type: "Feature",
            properties: {
              type: "billboard",
              style: {
                image: `${process.env.BASE_URL}imgs/zuobiao.png`,
                opacity: 1,
                scale: 0.9,
                rotation: 0,
                heightReference: Cesium.HeightReference.CLAMP_TO_GROUND,
                horizontalOrigin: Cesium.HorizontalOrigin.CENTER,
                verticalOrigin: Cesium.VerticalOrigin.BOTTOM,
                clampToGround: true,
                // disableDepthTestDistance: Number.POSITIVE_INFINITY,
              },
              buildName: item.buildName,
              id: item.id,
            },
            geometry: {
              type: "Point",
              coordinates: lnglat5[0],
            },
          };
          // 鼠标移入自定义弹出框
          // let handler = new Cesium.ScreenSpaceEventHandler(
          //   this.$viewer.scene.canvas
          // );
          // handler.setInputAction(function (movement) {
          //   Feature.disableDepthTestDistance = Number.POSITIVE_INFINITY;
          // }, Cesium.ScreenSpaceEventType.MOUSE_MOVE);
          showGeojson.features.push(Feature);
          // 地图上回显
          loadjsonEntitles = self.$drawControl.loadJson(
            showGeojson,
            true,
            true
          );
        }
