After adding a route to vue3 router. addRoute(), why is the page menu not updated?

[wenlongFam]

console.log(router.getRoutes()); The number of arrays is increased by 1, and the menu is not updated

`console.log(router.getRoutes()); //This array is 29，

//add route
router.addRoute('xitong2', {
path: '/projectbrowsing/duolianjixitong/xitong2',//
component: () => import('@/views/xitong/systemTabShow.vue'),
name: 'Xitong2',
meta: {
title: t('routers.xtyc'),
query: {
systemId: 'a02'
}
}
})

console.log(router.getRoutes()); //This array is 30，`

Prompt
Note that adding routes does not trigger new navigation. That is, the added route will not be displayed unless a new navigation is triggered

Does triggering a new navigation refer to a page jump or something?

this repo is not for questions. Use the channels mentioned at vuejs/router#1564 (comment)
example of new navigation: router.push()
