有没有办法知道在primeng multiselect中什么时候芯片被移除了？

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

@Component({
  selector: 'app-multiselect',
  template: `
    <p-multiSelect [options]="cars" [(ngModel)]="selectedCars" (onRemove)="onChipRemove($event)"></p-multiSelect>
  `
})
export class MultiselectComponent {
  cars: any[];
  selectedCars: any[];

  constructor() {
    this.cars = [
      { label: 'Audi', value: 'audi' },
      { label: 'BMW', value: 'bmw' },
      { label: 'Mercedes', value: 'mercedes' },
      { label: 'Volkswagen', value: 'volkswagen' }
    ];
    this.selectedCars = [];
  }

  onChipRemove(event: any) {
    // 处理芯片移除事件
    console.log('芯片被移除了:', event.value);
  }
}
