None of those things are defining characteristics of extraversion. (You seem to have confused the concept of extraversion with narcissism)
Extraverts tend to be outgoing. They enjoy socializing, attending parties, and other events that draw a crowd. But that doesn’t make them self-centered or attention-seeking. Quite the opposite. Their outward focus often manifests in being more focused on the needs of others, more likely to go out of their way to help friends in need, more likely to be the one others can call on for support.
