모바일에서만 컴포넌트를 활성화하는 방법이 있을까요?

[RGJ (Richard - Communiteq)]

The example is in that very topic

@system

import Component from "@glimmer/component";
import { service } from "@ember/service";

class MyComponent extends Component {
  @service capabilities;

  <template>
    {{#if this.capabilities.viewport.lg}}
      This text will be displayed for devices larger than the lg breakpoint
    {{/if}}

    {{#unless this.capabilities.viewport.sm}}
      This text will be displayed for devices smaller than the sm breakpoint
    {{/unless}}
  </template>
}
