NullInjectorError: R3InjecterError no provider for lightbox

Envirment

angular: 10 or 11

I created a test example of using ngx-lightbox. In the component:

import { Component, OnInit } from '@angular/core';
import { Lightbox } from 'ngx-lightbox';

@Component({
  selector: 'app-test-lightbox',
  templateUrl: './test-lightbox.component.html',
  styleUrls: ['./test-lightbox.component.scss']
})
export class TestLightboxComponent implements OnInit {

  constructor(private lightbox: Lightbox) { }

  ngOnInit(): void {
  }

}

the project can pass the complie processing.

When I opened the page and got the following error messages:

core.js:5980 ERROR Error: Uncaught (in promise): NullInjectorError: R3InjectorError(AppModule)[Lightbox -> Lightbox -> Lightbox]:
