如何在ng-select中初始设置值？

import { Component } from '@angular/core';
import { FormControl } from '@angular/forms';
import { NgOption } from '@ng-select/ng-select';

@Component({
  selector: 'app-my-component',
  template: `
    <ng-select [formControl]="selectedValue">
      <ng-option *ngFor="let option of options" [value]="option.value">{{ option.label }}</ng-option>
    </ng-select>
  `
})
export class MyComponent {
  selectedValue = new FormControl(); // 创建一个FormControl对象
  options: NgOption[] = [
    { value: 'option1', label: 'Option 1' },
    { value: 'option2', label: 'Option 2' },
    { value: 'option3', label: 'Option 3' }
  ];
}

export class MyComponent {
  selectedValue = new FormControl('option2'); // 设置初始值为'option2'
  // ...
}
