import { apiInitializer } from "discourse/lib/api";

export default apiInitializer((api) => {
    
    api.renderInOutlet("user-post-names",
    <template>
        {{#if @outletArgs.model}}
            <div class="uid-label-profile">
                UID:
                <span class="uid-value-profile">
                {{ @outletArgs.model.id }}
