ABP Framework version : 7.4.3

Please help me in below implementation, if user fills the form and with out saving (formgroup) navigate to another page, system should prompt confirmation popup for "cancel" and "confirm" popup if confirm=>navigate to new clicked page cancel=> stay in same page

Tried below: but it is always navigating to new page**, cannot remain in same page , if cancel is clicked **

ngOnInit(): void{ this.documentListDuplicateerror = false; this.currentUser = this.config.getOne('currentUser'); this.getDocumentConfig();

this.routeSubscription = this.router.events.subscribe((event) => {

  debugger;
  if (event instanceof NavigationEnd) {
    console.log('Navigation ended:', event.url);
    // Execute your logic here, e.g., update component state

    alert(event.url);
  }
});

}

public ngOnDestroy() {

if (this.apPayableForm.dirty) {

  const options: Partial&lt;Confirmation.Options&gt; = {
    hideCancelBtn: false,
    hideYesBtn: false,
    dismissible: false,
    cancelText: 'Cancel',
    yesText: 'Confirm'

  };

  this.confirmation
    .warn('DocHubManagement::DocHub:ChangesWillDiscard', 'DocHubManagement::DocHub:DiscardChanges', options)
    .subscribe((status: Confirmation.Status) => {

      if (status == Confirmation.Status.confirm) {

        return true;
      }
      else {
        //this.saveDocHubConfiguration();
        //if cancel then previous page
        if (this.routeSubscription) {
          this.routeSubscription.unsubscribe();
        }
      }
    });

}

return true;

//if (this.routeSubscription) {
//  this.routeSubscription.unsubscribe();
//}

}
