Why won't my blog post appear in SERPS?

I will preface by saying that this blog post was published months ago, and I have uploaded the sitemap to Google search console.

For some reason, despite the tags I've included, this specific blog post does not appear in Google SERPS. When I search for the relevant keywords/tags, the best I get is it brings up my blog page (which contains all of the blog posts), as opposed to linking directly to the specific blog post in question. (Please see images - The Atrium Lab Poised to Unite Cardano example is the correct outcome that I am aiming for. I search for the keywords and the article itself comes up in SERPS, not just the link to my blog page.)

The second image shows what comes up in SERPS when I search the keywords for the article I am trying to get to show up, however as you can see, the keywords only bring up a generic link to my blog page.

I have done nothing differently on this occasion than I do with all my blog posts, the others all come up on SERPS.

Please help.
