Angular -如何将按钮标签值添加到FormGroup

<form [formGroup]="myForm">
  <!-- 表单控件 -->
  <input type="text" formControlName="name">
  
  <!-- 按钮 -->
  <button (click)="addValue()">添加值</button>
</form>

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

  ngOnInit() {
    this.myForm = new FormGroup({
      name: new FormControl('')
    });
  }

  addValue() {
    const buttonLabel = '按钮标签值';
    this.myForm.patchValue({ name: buttonLabel });
  }
}
