How can I avoid that my logged-in user goes back to the login url in angular 16?

I have an angular 16 application and want to avoid that a user that is logged in can return to the login url. It should be possible with an authGuard, but I don't know how I could achieve this. In my app-routing module, I have this:

import { authGuard } from './guards/auth.guard';
import { LoginComponent } from './user/login/login.component';
import { ProfileComponent } from './user/profile/profile.component';
const routes: Routes = [
  { path: '', redirectTo: '/user/profile', pathMatch: 'full' },
  {
    path: 'user',
    children: [
      { path: 'login', component: LoginComponent },
      { path: 'profile', component: ProfileComponent, canActivate: [authGuard] },

      { path: '', redirectTo: 'profile', pathMatch: 'full' },
      { path: '**', redirectTo: 'profile', pathMatch: 'full' },
    ],
  },

  { path: '**', redirectTo: '/user/profile', pathMatch: 'full' }
]
@NgModule({
  imports: [RouterModule.forRoot(routes, { useHash: false })],
  exports: [RouterModule],
})
export class AppRoutingModule {}

and my authGuard looks like this:

import { CanActivateFn, Router } from '@angular/router';
import { AuthService } from '../user/auth.service';
import { inject } from '@angular/core';
import { JwtHelperService } from '@auth0/angular-jwt';

export const authGuard: CanActivateFn = (route, state) => {
  const token = localStorage.getItem('access_token');
  const jwtHelper: JwtHelperService = inject(JwtHelperService);
  const authService = inject(AuthService);
  if (token && !jwtHelper.isTokenExpired(token)) {
    return true;
  } else {
    authService.logout();
    return false;
  }
};

The token authentication works fine, and the user/profile url is properly protected by the authGuard. For user/login however, this does not make sense, since everyone should be able to go to this page.

I tried to put the authGuard at the end of the user path, so it all parent and children paths are guarded, but that causes issues with finding the correct path. I also tried to check in the authGurad if (state.url == '/user/login') {router.navigate(['/user/profile']} but this causes a circular reroute.
