This is really cool! this is just for the message thread? is this announcer (since it is much more powerful than the one I made) something we want to start adapting into new components in the furture/update existing announcers?

We can reuse this throughout. I just super quickly copy-converted over the underlying library as it was very small so should be essentially a no-op but we can definitely integrate this into calling as well to avoid multiple announcement. Honestly though we need a stateful-driven announcer instead of the announcements being driven at the individual react-component layer as the react-components don't have context of the whole app to make a good, informed decision about whether to announce or not
