Update to documentation for hosting Wordpress on Unit behind Nginx reverse proxy? Any working examples with complete config?

[Bill]

Hello,

This tutorial for putting Wordpress on Unit behind Nginx reverse-proxy

 Installing WordPress with NGINX Unit
  https://www.nginx.com/blog/installing-wordpress-with-nginx-unit/

was written back in 2018, before 'routes' etc were added to Unit.

This up to date documentation

 WordPress
  https://www.nginx.com/blog/installing-wordpress-with-nginx-unit/

doesn't address Reverse-proxying.

This doc

 NGINX Integration
  https://unit.nginx.org/howto/integration/

talks about "Fronting Unit with NGINX" but then only gives an example of proxying the Unit Control API.

Is there a single document, showing complete configuration, for hosting Wordpress on Unit behind an Nginx Reverse-proxy that's up-to-date with latest version of Unit,

AND

includes detail/example of putting it all in a subdirectory of the Nginx frontend?

So, for example,

    https://frontend.example.com/blog, on Nginx
  <->
    https://backend.example.com:10000, Wordpress on Unit

?

I've been trying for a long time to get it working with Wordpress on Nginx.
Couldn't get that to work and there's no documentation or support for that configuration afaict.
I did find other people's posts that tried and gave up on it too.

I found these articles for using Unit on the backend host instead.  Hoping to get an updated config them to do the full reverse proxy setup.
