Native侧获取env具有线程限制，如何在C++子线程触发ArkTS侧回调

static napi_value AddTSFCallback(napi_env env, napi_callback_info info) { 
    // ...  
    napi_get_cb_info(env, info, &argc, args, nullptr, nullptr); 
    auto contextData = new ContextData; 
    contextData->args = strBuff; 
    // 创建线程安全函数对象，注册绑定callback和call_js_cb回调 
    napi_create_threadsafe_function(env, args[2], nullptr, asyncName, MAX_MSG_QUEUE_SIZE, INITIAL_THREAD_COUNT, nullptr,nullptr, nullptr, CallJsFunction, &tsFun); 
    thread t(AddFunc, static_cast<void *>(contextData));   // 创建C++子线程，处理业务逻辑 
    t.detach(); 
    return nullptr; 
} 
 
static void AddFunc([[maybe_unused]] napi_env env, void *data) { 
    ContextData *contextData = static_cast<ContextData *>(data);       // 解析上下文，业务处理，两数相加 
    contextData->result = add(contextData->num1, contextData->num2);   // 将结果置入上下 
    napi_call_threadsafe_function(tsFun, data, napi_tsfn_blocking);    // 调用线程安全函数 
} 
 
static void CallJsFunction(napi_env env, napi_value callBack, [[maybe_unused]] void *context, void *data) { 
    ContextData *contextData = static_cast<ContextData *>(data); 
    // ...  
    napi_value callBackArgs = nullptr; 
    napi_create_double(env, contextData->result, &callBackArgs); 
    napi_value callBackResult = nullptr; 
    napi_call_function(env, undefined, callBack, 1, &callBackArgs, &callBackResult);    // 调用callback，反馈结果到ArkTS应用侧 
    DeleteContext(env, contextData); 
}
