When logging into Nextcloud from your browser a new session is established and added to the security tab in the settings. I like to have them organized and renamed so that i know which device and app they are for, but if it is your own session it just shows "This session". This annoys me because I have to log into Nextcloud from a second device or privat Tab to rename this session as well.

Describe the solution you'd like
The ability to rename my own session. Maybe add a little icon before or behind the name to display that the session you are looking at is currently your own session. (also not adding the buttons for Revoking and Wiping as this would be the same as just logging out)

No files, tests, or entry points are identified in the issue. Start by locating the security settings session list and the server-side session handling, then trace how the current session is distinguished from other sessions. Done means the own session can be renamed while retaining its own-session indicator and without exposing revoke or wipe actions for it.
