How to set latex-workshop.intellisense.commandsJSON.replace correctly？

[EVISTIX1]

Translation from @James-Yu

I'd configure auto-completion of LaTeX with VSCode. I got a tutorial from zhihu.com saying to add

    "\\int_{}^{}": {
        "snippet": "\\int_{$1}^{$2}$3\\,\\mathrm{d}",
        "detail": "定积分"
      },

to file C:\Users\用户名\.vscode\extensions\james-yu.latex-workshop-版本号\data\commands.json

to get the intellisense. However, due to LW updates, command.json is overwritten.

So I re-read the LW documentation and discovered a latex-workshop.intellisense.commandsJSON.replace config to change and remove auto-completion items.

I followed the official instruction but failed. Can't find other tutorials so I came here.

我英文不好，不知道该如何用英文提问，在谷歌搜索多次也无果。这个项目是中国人开发的，我拿中文提问应该可以吧？
问题如下：
我想在配置VScode中配置LaTeX的代码自动补全，在知乎上搜到的教程是在

C:\Users\用户名\.vscode\extensions\james-yu.latex-workshop-版本号\data\commands.json

内添加如

"\\int_{}^{}": { "snippet": "\\int_{$1}^{$2}$3\\,\\mathrm{d}", "detail": "定积分" },

的代码即可在VScode内完成代码补全。但是貌似是因为latex-workshop的更新，command.json的内容又被覆盖掉了。
因此我重新阅读latex-workshop的官方文档，发现要在latex-workshop.intellisense.commandsJSON.replace中修改和删除自动补全条目，但是我按照官方文档的示例进行操作没有成功，网上也没找到类似的教程,遂来提问。

latex-workshop.intellisense.commandsJSON.replace is for modify and remove existing items, not including new ones. If you'd add new ones, you may choose to make them vscode snippets.

latex-workshop.intellisense.commandsJSON.replace 是用来修改和删除的，所以不能添加新条目。你可以把你的命令做成一个VSCode的snippet。
