Help with SEO Blog Title showing up FB/ Social

Hi,

I've tried to adjust how my blogs title shows up when posting to Facebook. I've attached a photo of mine, where it says "Enoki Threads" in bold at the bottom, I want that to be the blog title.
I did find a setting in Marketing: SEO: Search Appearance but it will be a permanent title, and won't change when I post a new blog.

I attached a photo of someones blog post on FB and you can see they have a bold title of that exact blog post.

How do we do it on here? The marketing:SEO doesn't seem to be a fix for this?

First photo is my site: https://www.enokithreads.com/blog/veganairlines
Second photo is how I want my post to show up on FB.

A squarespace support rep said this feature isn't available on here, unless it's custom coding?
