flashMessages is not working in newly create ember app

[Randhir-93]

1. Create a new app using ember new testApp
2. Installed latest version of ember-cli-flash
3. created a test component
   `import Component from "@glimmer/component";
   import { inject as service } from "@ember/service";

export default class TestComponent extends Component {
@service flashMessages;

constructor() {
    super(...arguments);
    setTimeout(() => {
        this.flashMessages.alert("dsfsf");
    }, 1000)
}

}`
Calling TestComponent from application.hbs but flash message is not showing.

Make sure you are also displaying the message queue somewhere in the template:

{{#each this.flashMessages.queue as |flash|}}
  <FlashMessage @flash={{flash}} />
{{/each}}
