		'history_cleared',
		'poll_voted',
		'poll_closed',
		'recording_started',
		'recording_stopped',

are all sent via signaling messages.

Polls will only contain specific votes when the poll is not anonymous, otherwise the sum of all votes will be shown.

• Split notify methods into separate calls for chat and system messages.

poll_voted send voting data (total votes and each option results) with the updated poll (If anonymous there is no poll_voted)
poll_ended send entire poll data including users ( total votes, each option results with list of voters) (if anonymous, send total votes and total number for each option)

All listed sys messages are working, with a bonus value that poll system messages are enough to cover the poll process with no need to send a request getPollData 🔥

As a follow up and not critical, we can craft sys message chat relay thread_created so it transfer the thread object upon initialization (replacing a request getSingleThread)
