Ionic 4 - Navigating from blank page to tabs page

Ionic Framework
1

Has anyone tried navigating from a one page to tab page(generated in ionic sample code) with minimal changes or no changes.

Below is code snippet -

app.routing.ts

const routes: Routes = [
  { path: '', loadChildren: './login/login.module#LoginPageModule' },
  { path: 'tabs', loadChildren: './tabs/tabs.module#TabsPageModule' },
  { path: 'profile', loadChildren: './profile/profile.module#ProfilePageModule' }
]

login.page.ts
registerUser(){
      this.navCtrl.navigateRoot('profile')
 }

profile.page.ts

createProfile() {
      this.navCtrl.navigateRoot('tabs')
  }

Can similarly we navigate from profile page to tabs page, I am using the above approach. How to change my tabs.routing.ts to make it work as it works on any normal tabs application loading into dom.
