Docusaurus：如何在每个文档页面上显示“编辑此页面”链接？

Question

我认为这将是一个相当简单的问题，但对于我的一生，我无法找出答案。

我想要的是：

• 我想显示我的 Docusaurus 文档页面，并在每个页面上都有“编辑此页面”链接。

我尝试过的：

• 我的理解是，通过配置该editUrl属性，我会自动获得该行为（参见https://docusaurus.io/docs/api/plugins/@docusaurus/plugin-content-docs#editUrl）。

问题：

• 页面显示正常，但没有显示“编辑此页面”链接！

可能有助于解决问题的相关信息：

我有一个 docusaurus 网站，具有以下参数：
