WordPress "Hello World!" plug-in adds itself to all new pages?
I created my first PHP WordPress plugin and find that it ads itself to any new page, but I want to be able to add it when I want to.
I was not sure how much of a header, or any header, may be required by WP to be considered a plug-in.
I zipped it up, along with an empty index.html file, then zipped it into hello.zip. I added the plugin using the WP Admin panel, and found it worked.
BUT, any new page gets "Hello World!"
How do I prevent it from going into every page? And how do I place the plug-in on a page, where I would like it to appear?

It's worth mentioning that a more flexible way of using a plugin to add content to a page is by defining a new shortcode that you can add to your page, or perhaps by defining a Gutenberg block that can be selected by the user. Hard-coding which page content displays on is very limiting.

I would like to hear more about that idea of defining a Gutenberg block that can be selected by the user. Does the "user" mean the developer? Or the actual user?
