Joel, if I remember correctly, the Editor component made available by the @tinymce/tinymce-react package can accept a prop tinymceScriptSrc which must be the path to the location of the TinyMCE script in your /public directory (this prop is only needed when you're self-hosting the script). In my case, the value I passed to the prop was such: tinymceScriptSrc="/tinymce/tinymce.min.js". I hope that helps, if not, let me know.
