Ios 如何使用UIDocumentBrowserViewController对应用程序进行UI测试

我用UIDocumentBrowserViewController编写了一个应用程序。 从应用程序开始录制UI测试时，一旦我选择了文档，就会出现错误

时间戳事件匹配错误：找不到匹配元素

而是使用启动和记录视图层次结构

printd(XCUIApplication().debugDescription)

我得到以下结果：

Path to element:

Query chain:
→Find: Target Application ‚xxx.TestApp'
  Output: {
    Application, pid: 1564, label: 'TestApp'
  }

文档（在此运行期间为3个）不可见。所以我无法访问它们

是否有任何必要的配置将这些包含在视图层次结构中（带有标签？）
