Logout facebook ionic 4

Ionic Framework
1

Hello,
I have a little worry.
I followed this tutorial and my problem is that FB does not want to disconnect.
I get that in the console “FB.logout() called without an access token”

  logout() {
      this.fb.logout().then(res => {
      this.nativeStorage.remove('facebook_user');
      this.router.navigate(["/"]);
    }, err => {
      console.log(err);
    });
  }

I searched but I do not find how to disconnect if the user wishes.

thank you in advance
