## PollModeCompletionHandler Class

Handles CIBA poll mode token delivery where the client periodically polls the token endpoint to retrieve tokens\.
In poll mode, the authenticated request is stored and remains available until the client retrieves it or it expires\.
Supports optional long\-polling to reduce polling frequency and improve efficiency\.

public class PollModeCompletionHandler : Abblix.Oidc.Server.Features.BackChannelAuthentication.AuthenticationNotifiers.AuthenticationCompletionHandler
