Insert text below username?

You could also use the API if you need to adjust the content programmatically (to check the user, the post, etc.).

For example:

api.decorateWidget("poster-name:after", (dec) => {
    // "dec.attrs" to access the attributes of the post
    return dec.h("div", "meta.discourse.org");
  });
.topic-meta-data .trigger-user-card {
    flex-direction: column;
    align-items: flex-start;
}
