在配置了formGroup的表单中应该如何使用垫-滑块？角度材料

<form [formGroup]="myForm">
  <!-- 表单控件 -->
</form>

<div formGroupName="sliderGroup">
  <mat-slider formControlName="sliderControl"></mat-slider>
</div>

import { FormGroup, FormControl } from '@angular/forms';

export class MyComponent {
  myForm: FormGroup;

  constructor() {
    this.myForm = new FormGroup({
      sliderGroup: new FormGroup({
        sliderControl: new FormControl()
      })
    });
  }
}

export class MyComponent {
  // ...

  ngOnInit() {
    this.myForm.get('sliderGroup.sliderControl').valueChanges.subscribe(value => {
      console.log('Selected value:', value);
    });
  }
}
