Authorization via plugin

[BlinCT]

Hello everyone. 
Maybe someone has set up a similar connection? 
But only without LDAP, since I don't have it. 
I'm trying to authorize using OAuth2/OpenID. There is a description on the official website, but it doesn't work. And most importantly, when I log in, server are asked about choosing a server, and what should you specify there? 
I would be grateful if someone has set this up and can explain how to do it.
It is interesting that such authorization on the example of portainer creates a user that was specified in authentik, and he can already configure what he needs. This is also interesting how it works.
Thanks.

The part regarding choosing a server can usually be resolved by clearing your browser cache. Not sure about the rest of it. I've never setup LDAP in Jellyfin before.

There is a guide over in the walk-through subforum for Authentik, though.

so I wrote that I don't need LDAP, I don't have it. And I need another authorization, OAuth2/OpenID
