Try this:

<button (click)="change()">change</button>
<div  [class.disabled]="!toggle"  (click)="toggle && expand()" [ngClass]="{'old': toggle, 'new': !toggle}"class="old">
  Hello
</div>

in CSS:

.disabled {
  cursor: not-allowed;
}

Change your files like a write below:

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'my-app',
  styleUrls: ['./app.component.scss'],
  templateUrl: './app.component.html',
})
export class AppComponent implements OnInit {

  public toggle: boolean = true;

  ngOnInit(): void {

  }

  public change(): void {
    this.toggle = !this.toggle;
  }

  public expand(): void {
    if (this.toggle) {
      alert('hi');
    }
  }

}

And your html file:

<button (click)="change()">change</button>
<div (click)="expand()" [class.new]="!toggle" class="old">
    Hello
</div>
