How to use named outlets in Angular?

Question

Angular

Friends, tell me... I'm making an application and I need to load the necessary routes in the popup window... I made child components and set up routing, but it doesn't work, what could be the matter...
app-routing.module.ts

import {NgModule} from '@angular/core';
import {RouterModule, Routes} from '@angular/router';
// import {AuthComponent} from './auth/auth.component';
// import {LoginComponent} from './auth/login/login.component';
// import {SignupComponent} from './auth/signup/signup.component';
import {PublicComponent} from './public/public.component';
import {LoginComponent} from './public/login/login.component';
import {SignupComponent} from './public/signup/signup.component';

const routes: Routes = [
 {path: '', component: PublicComponent, pathMatch: 'full'},
 {path: '', component: PublicComponent, children: [
     { path: 'login.html', component: LoginComponent, outlet: 'login' },
     { path: 'signup.html', component: SignupComponent, outlet: 'signup' }
   ] }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})

export class AppRoutingModule {}

public.component.html
