如何使用angular 9 reactive forms中的复选框从多选框中选择所有选项

<form [formGroup]="myForm">
  <label>
    <input type="checkbox" formControlName="option1"> Option 1
  </label>
  <label>
    <input type="checkbox" formControlName="option2"> Option 2
  </label>
  <label>
    <input type="checkbox" formControlName="option3"> Option 3
  </label>
  <!-- 添加更多的复选框，如果需要 -->
</form>

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

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponentComponent implements OnInit {
  myForm: FormGroup;

  constructor(private formBuilder: FormBuilder) { }

  ngOnInit() {
    this.myForm = this.formBuilder.group({
      option1: false,
      option2: false,
      option3: false
    });
  }
}

selectAllOptions() {
  this.myForm.patchValue({
    option1: true,
    option2: true,
    option3: true
  });
}

<button (click)="selectAllOptions()">Select All Options</button>
