Install Wordpress inside CI4 project

I don't believe my case is the ideal one to answer your question, I have a private site, only local, but except for the rules for using a remote server, especially the server security, of course, it's very similar to the so-called real world.
I used CI3 and I can assure you that CI4 is much easier.
I just created a folder in public, blog, and installed wordpress in this folder. To access, http://localhost/blog. It's important to keep in mind that if you wanted, for example, just the blog, without CodeIgniter, the configuration would be the same, that is, wordpress would be installed in the area equivalent to '/public' of CodeIgniter on the server.
The entire security issue remains unchanged, the blog continues to have its own security without any contamination to CodeIgniter items.
