Hi, I’m using version 3.2.0.beta4-dev for local development and plugin API version 0.8.7 for plugin development. However, due to recent changes in Discourse, the addPostMenuButton and component:topic-list functions have been modified. How can I use api.registerValueTransformer for these API functions? Additionally, which plugin API version should I use to match with 3.2.0.beta4-dev to ensure compatibility with api.registerValueTransformer? Here’s my code for addPostMenuButton: api.addPostMenuButton("togglePostButton", (model) => { const siteSettings = api.container.lookup("site-settings:main"); const posts = siteSettings.posts; const array_of_posts = posts.split("|"); const postId = model.id; const postIdstr = postId.toString(); const isPost = array_of_posts.includes(postIdstr); return { action: "togglePost", position: "first", className: isPost ? "button.topic_hidden custom-class-hidden" : "button.topic_visible custom-class-visible", icon: isPost ? "far-eye-slash" : "far-eye", title: isPost ? "Hide Post" : "Show Post", }; }); And here’s my code for component:topic-list: api.modifyClass("component:topic-list", { pluginId: "post-toggle", didInsertElement: function () { this._super(); const topics = this.topics; for (let key in topics) { if (topics.hasOwnProperty(key)) { let newTopicLatest = []; const topic_id = topics[key].id; const topic_posters = topics[key].posters; topic_posters.forEach((poster) => { if (poster && poster.extras !== null && poster.extras.includes("latest")) { newTopicLatest = poster["description"].split(","); } }); let userListLatest = newTopicLatest; if (userListLatest.length > 1 && userListLatest[0] === "Original Poster") { userListLatest = userListLatest.slice(1); userListLatest[0] = userListLatest[0].trim(); } let i = 0; const element = $('tr[data-topic-id="' + topic_id + '"]').find( "a[data-user-card]" ); if (element.length > 0) { element.each(function () { const poster_inside = topic_posters[i]; if (poster_inside !== undefined && Object.keys(poster_inside).length !== 0) { const userElement = $(this); if (!userListLatest.includes(poster_inside.user.id.toString())) { userElement.hide(); } } i++; }); } } } } }); Can anyone help me with this?

Yes, I have read about that topic, implemented changes based on the new plugin API updates, and figured out component:topic-list as well.

I updated my local development Discourse to version 3.5.0.beta2-dev, and the plugin API version is 2.1.1. How can I use api.registerValueTransformer for the addPostMenuButton and component:topic-list functions?
