如何在OpenLayers中实现带箭头标记的线串动画？

我已经能基于数据在地图上绘制线串，但想实现带箭头标记的线串动画（如附图所示），恳请OpenLayers社区的各位帮忙解决此问题。

我的myLayerFeature中存储着一组带坐标的要素列表，目前通过循环遍历每个要素来绘制线条，并参考要素移动动画的实现逻辑添加箭头图像，相关代码如下：

遍历要素调用动画函数 #

$(myLayerFeature).each((index, mapitem1) => {
    moveArrowOnLine(mapitem1.geometry);
});

箭头动画核心函数 #

function moveArrowOnLine(geometry) {
    debugger
    var startCoordinates = geometry.coordinates[0];
    var endCoordinates = geometry.coordinates[1];

    const startMarker = new ol.Feature({
        type: 'icon',
        geometry: new ol.geom.Point(startCoordinates),
    });
    const endMarker = new ol.Feature({
        type: 'icon',
        geometry: new ol.geom.Point(endCoordinates),
    });
    const position = startMarker.getGeometry().clone();
    const geoMarker = new ol.Feature({
        type: 'geoMarker',
        geometry: position,
    });

    const styles = {
        'route': new ol.style.Style({
            stroke: new ol.style.Stroke({
                width: 6,
                color: [237, 212, 0, 0.8],
            }),
        }),
        'geoMarker': new ol.style.Style({
            image: new ol.style.Icon({
                scale: -0.04,
                anchor: [0, 0.8],
                anchorXUnits: 'fraction',
                anchorYUnits: 'fraction',
                opacity: 1,
                projection: '3857',
                src: './images/left-arrow.png',
            }),
            image: new ol.style.Circle({
                radius: 20,
                fill: new ol.style.Fill({ color: 'red' }),
                stroke: new ol.style.Stroke({
                    color: 'black',
                    width: 2,
                }),
            }),
        }),
    };

    const vectorLayer = new ol.layer.Vector({
        source: new ol.source.Vector({
            features: [geoMarker, startMarker, endMarker],
        }),
        style: function (feature) {
            return styles[feature.get('type')];
        },
    });
    map.addLayer(vectorLayer);
    startAnimation();
}
