How do I know which page I'm on if there's no change in the address bar?

Question

Google Chrome

Hello.
Let's say there is a forum where each user can create a topic and edit it.
After creating a topic, it is assigned a number, and the link to the topic looks something like this: forum.domen/
theme2678 stands still forum.domen/theme2678, not forum.domen/theme2678edit, for example.
I'm wondering why this is happening and is there a way to link to the edit page in this scenario?

Answer 1

It doesn't go anywhere unless it's in the address bar.
This is a dynamic page change. There is no actual transition.
Depending on the wishes of the site developer - with such a dynamic change, the contents of the address bar may or may not change. But the line here is secondary.

Answer 2

It depends on the site settings, there is nothing you can do about it.
