在Firefox扩展中使用带有2个面板的侧边栏时，应该如何定义manifest.json

Question

考虑下面显示的示例，该示例取自MDN，并稍作修改以在侧边栏文件夹中包含两个侧边栏面板：

var thisPanel = browser.extension.getURL("/sidebar/this.html");
var thatPanel = browser.extension.getURL("/sidebar/that.html");
function toggle(panel) {
  if (panel === thisPanel) {
    browser.sidebarAction.setPanel({panel: thatPanel});
  } else {
    browser.sidebarAction.setPanel({panel: thisPanel});
  }
}
browser.browserAction.onClicked.addListener(() => {
  browser.sidebarAction.getPanel({}).then(toggle);
});

如何在manifest.json中定义sidebar_action属性？可以吗？

"sidebar_action": {
    "default_icon": "/icons/default_icon.svg",
    "default_title" : "Title",
    "default_panel": "/sidebar/this.html",
    "open_at_install": false
  },
