Outstanding. I’ll have a look and see what might work best. That said, I’m an old man so when I see terminology like “external tools” my brain freezes. Will give a go though.
Dumb questions don't exist!
Try nostr:npub1yzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesnxrf8q https://yakihonne.com/
Or if you're a power user, using external tools to formated you (Markdown formatted) long-form content:

and (which I'm maintaining) https://www.drupal.org/project/nostr_content_nip23 but that's a complex way which is far from polished and a out-of-the-box ready solution

Use the tools that fits the best for you.
