Vaadin14+Spring websocket authentication

Hello.
I have an ApplicationEventPublisher and some @EventListener’s
When Push(transport=WEBSOCKET_XHR) is in use everything is fine.
If I switch to WEBSOCKET Push mode I can’t receive any message in @EventListener with Spring report An Authentication object was not found in the SecurityContext.
Seems like Spring doesn’t know any about SecurityContext after http-upgrade was in place.
Did i miss something in configuration or is it a wrong way to proceed with application events in Vaadin+Spring?

Vaadin 14.8.20
Spring-boot 2.6.7.

Thanks in advance.
