Nginx, rewrite - how to change the URL in the address bar?

Question

Nginx

Hello.
In the thread How to rewrite in Nginx without changing the URL in the address bar? they ask how to make a redirect without changing the URL in the address bar, but my situation is exactly the opposite!
I wanted to make beautiful short addresses. For example, instead of

https://www.domain.ru/mod/bigbluebuttonbn/view.php?id=156

do
https://www.domain.ru/webinar-156.html
Write inside server {} rule -

rewrite ^/webinar-(.*) https://www.domain.ru/mod/bigbluebuttonbn/view.php?id=$1 last;

And everything seems to work, if you enter in the address bar https://www.domain.ru/webinar-156.html, then what you need opens, but at the same time the address in the address bar changes to

https://www.domain.ru/mod/bigbluebuttonbn/view.php?id=156

But then I would like to hide it ...
What could be the matter?
Thank you.
