Is it possible to terminate user session ad hoc?

[PavelKochkin2]

I have a task to be able to terminate a user (for example, if it is a malicious user). So far, I've been able to lock a user through lockout enabled, but it applies only on the next user login, which doesn't fit in my case. We don't use JWT, just usual .net core cookie. Any chance that this ad hoc session invalidation can be done using Identity Administrator UI? Thanks in advance
