What is the name of such a hook in WordPress?

Question

CMS

Good afternoon
There is a post. And you need to display a certain html block immediately after it
. This is how a plugin is needed. (Exactly the plugin)
In the plugin I do manipulations with the database and collect the html block into a variable.
Now. I can't find a suitable hook for this... there is the_content and you can get content and output after it, but that's not what you want. What is needed is a type hook after the post.
That is, the plugin outputs something after the post.
Help me please!!!!

What's wrong with the_content? All that needs to be added after the post - he does it. Set a higher priority - for example 1000 and it will be at the very end - what you need.

If you haven't found a suitable hook, you can create your own custom hook or handle buffered output (with attention to load).
