Override quoteState opts?

In case someone else comes across this, I found how to override the quoteState opts in quote-button.js insertQuote. Full code below, which will replace the username in quotes in specified categories with both the toolbar quote and the selection quote button.

<script type="text/discourse-plugin" version="0.8">
const controller = api.container.lookup('controller:topic');
const anon_categories = [5, 6, 14, 15, 16, 17, 18]

    function buildQuote(post, contents, opts = {}) {
      if (!post || !contents) {
        return "";
      }
    
        let anon_name = ``;
        // console.log(anon_categories, controller.get("model.category_id"))
        if (anon_categories.includes(controller.get("model.category_id"))) {
            anon_name = `Anonymous`;
        } else {
            anon_name = opts.username || post.username;
        }
        
        const params = [
            anon_name,
            `post:${opts.post || post.post_number}`,
            `topic:${opts.topic || post.topic_id}`
          ];
    
        if (opts.full) params.push("full:true");
    
        return `\n[quote="${params.join(", ")}"]\n${contents.trim()}\n[/quote]\n\n`;
    }
    
    api.modifyClass('controller:composer', {
        pluginId: 'anonymize-quotes',
        actions: {
            importQuote(toolbarEvent) {
              const postStream = this.get("topic.postStream");
              let postId = this.get("model.post.id");
        
              // If there is no current post, use the first post id from the stream
              if (!postId && postStream) {
                postId = postStream.get("stream.firstObject");
              }
        
              // If we're editing a post, fetch the reply when importing a quote
              if (this.get("model.editingPost")) {
                const replyToPostNumber = this.get("model.post.reply_to_post_number");
                if (replyToPostNumber) {
                  const replyPost = postStream.posts.findBy(
                    "post_number",
                    replyToPostNumber
                  );
        
                  if (replyPost) {
                    postId = replyPost.id;
                  }
                }
              }
        
              if (postId) {
                this.set("model.loading", true);
        
                return this.store.find("post", postId).then(post => {
                  const quote = buildQuote(post, post.raw, {
                    full: true
                  });
        
                  toolbarEvent.addText(quote);
                  this.set("model.loading", false);
                });
              }
            }
        }
    });
    
    api.modifyClass("component:quote-button", {
        pluginId: 'anonymize-quotes',
        actions: {
            insertQuote() {
                let anon_name = ``;
                // console.log(anon_categories, controller.get("model.category_id"))
                if (anon_categories.includes(controller.get("model.category_id"))) {

                this.attrs.quoteState.value.opts.username = anon_name;
                this.attrs.selectText().then(() => this._hideButton());
                console.log(anon_name, this.attrs.quoteState.value.opts)
              }
        }
    });
    
    const composerController = api.container.lookup("controller:composer");
    const quoteButton = api.container.lookup("component:quote-button");
