Refreshing certain fragment of the page with communication panel action

Dear Creatio Community,

I have a similar question to the one that was asked few years back:

https://community.creatio.com/questions/how-can-you-refresh-timeline-feed-or-next-steps-component-code

My goal is similar but with difference that I want to refresh my timeline from a action that will happen in communication panel page. For example I click a create activity button in that panel, should add the activity and refresh the timeline.

The enable live update does not work.

Best regards,

Krzysztof.
