CanDeactivateGuard redirect to the home page

Question

I want when someone press browser's back button to warn him and if he press ok then i will redirect to Home Component. I use CanDeactivate Guard and i want to change the nextState of CanDeactivateGuard. I tried to change the nextState :

nextState = { root: currentRoute, url: '/' }

but always redirect me to the previous component

can-deactivate-guard.service.ts

import { Injectable } from '@angular/core';
import { Observable } from 'rxjs';
import { CanDeactivate, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router';

export interface CanComponentDeactivate {
   canDeactivate: () => Observable<boolean> | Promise<boolean> | boolean;
}

 @Injectable({
  providedIn: 'root'
 })
 export class CanDeactivateGuard implements CanDeactivate<CanComponentDeactivate> {

 canDeactivate(component: CanComponentDeactivate,
 currentRoute: ActivatedRouteSnapshot,
 currentState: RouterStateSnapshot,
 nextState?: RouterStateSnapshot
 ): Observable<boolean> | Promise<boolean> | boolean {

 nextState = { root: currentRoute, url: '/' }// try this, but dosen't work
 return component.canDeactivate();
 }
}

My components code. pressContinue is just a boolean in case someone press continue button for the next component.

  canDeactivate() {
  if (this.pressContinue) {
     return true;
   } else {
     return confirm('Are you sure?');
   }
  }

I don't know if it's the best solution but i change the logic on my component to redirect me to homepage and it's working!

canDeactivate() {
if (this.pressContinue) {
  return true;
 } else {
  var resp = confirm('Are you sure?');

  if(resp == true)
  window.location.href = '';

  return false;
 }
}
