Could we PLEASE get more docs on subscriptions / observables?

They sem to me extremely useful and important and there is just about no documentation on them at all. Not in jsdoc and the docs page is extremely short and there are almost no comments anywhere. So much of the rest of this wonderful library is extremely well documented - in particular when we can also use the TanStack Query docs but there is this one super useful part that is relegated to a Extra information Subscriptions / WebSockets section. Some more detailed explanations of how these things work and behave would be extremely appreciated. Thank you very much for all the hard work thus far and I wish you all the best in the future.
