electron右键菜单快捷键无效？

Question

代码如下，用鼠标操作没问题，但是快捷键不行，哪里有问题吗？？？

const contextMenu = Menu.buildFromTemplate([
      {
        label: '图片另存为...',
        accelerator: "ctrl+s",
        click: () => {
          got.get(srcUrl).then(async (Response) => {
            const chunk = Buffer.from(Response.rawBody)
            const imgType = imageType(chunk)

            const { filePath, canceled } = await dialog.showSaveDialog({
              title: '图片另存为',
              defaultPath: path.resolve(__dirname, "../public/upload/" + randomstring.generate(10) + `.${imgType.ext}`)
            })
            if (!canceled) {
              fs.writeFileSync(filePath, chunk)
            }
          }).catch((e) => { })
        },

      }
    ])
