You can also use iconHTML instead of manually added the icon.
Something like this should work:

import { apiInitializer } from "discourse/lib/api";
import { iconHTML } from "discourse/lib/icon-library";

export default apiInitializer((api) => {
  api.onPageChange(() => {
    const btnIcon = document.querySelector("#create-topic .d-icon");
    if (btnIcon) {
      btnIcon.outerHTML = iconHTML("plus");
    }
  });
});
