我尝试使用Autodesk.Viewing.TOOL_CHANGE_EVENT将标记数据插入到云数据库中。但是，似乎在通过`markupsExtension.generateData（）提取标记数据之前触发了此事件

//Make sure the extentions loaded
 viewer?.current?.loadModel(path.urlPath, {}, function onSuccess() {
 viewer?.current?.loadExtension("Autodesk.Viewing.MarkupsCore");
viewer?.current?.loadExtension("Autodesk.Viewing.MarkupsGui");
}); 

 React.useEffect(() => {
    viewer?.current?.addEventListener(
      Autodesk.Viewing.TOOL_CHANGE_EVENT,
      (x) => {
        if (x.active && x.toolName === "markups.core") {
          getAllMarkupsFromDatabase(viewer.current);
        } else if (!x.active && x.toolName === "markups.core") {
        //here the event close before getting the data
          saveMarkupsToDatabase(viewer.current);
        }
      }
    );
  }, [isGeometryLoaded]);
  
//Save the markups data.
async function saveMarkupsToDatabase(viewer: any) {
  const markupsExtension = await viewer.loadExtension(
    "Autodesk.Viewing.MarkupsCore"
  );

  const markupsData = await markupsExtension.generateData();
  console.log({ markupsData });

  //Save to database

   localStorage.setItem("markups", markupsStringData);
 

}

我不确定是否有一种方法可以在关闭标记扩展之前获得数据。
