How to create a route group in vue-router?

Question

Vue.js

Hello!
I can't figure out how to create a route group. I tried through children but it works through the parent router-view i.e. not through the very first router-view, but descends from parent to child, etc., as I understand it.

I need this to set one meta per route group.
those. I want so:

{
        path:"/admin",
        name: 'Admin',
        meta:{isAdmin:true},
        component: () => import('./views/admin/Main.vue'),
        children:[
            {
                path:'user',
                name:'allUsers',
                component: () => import('./views/admin/User/allUsers.vue'),
            },
            {
                path:'products',
                name:'allProducts',
                component: () => import('./views/admin/Products/allProducts.vue'),
            },
        ]
    },

To not write like this all the time

{
        path:"/admin",
        name: 'Admin',
        meta:{isAdmin:true},
        component: () => import('./views/admin/Main.vue'),
},
{
         path:'/admin/user',
         name:'allUsers',
meta:{isAdmin:true},
         component: () => import('./views/admin/User/allUsers.vue'),
},
{
         path:'/admin/products',
         name:'allProducts',
meta:{isAdmin:true},
         component: () => import('./views/admin/Products/allProducts.vue'),
},

Or will you still have to add meta to all routes?
