Introvert and extrovert are pretty blunt terms, there are people who find it easy to talk to others and those who find it difficult even when necessary, these might but do not need to correspond to wanting to talk to others (among other nuances). Introvert usually groups those who have difficulty and those who dislike talking to others, but with work from home that grouping doesn’t necessarily make sense.

If it’s harder for you to initiate conversations, bumping into people and common office occurrences can make it easier to start talking. But if you don’t like talking to others than bumping into people can feel intrusive.
