Even introverts need social connection (perhaps more so) - research here [1]. Introverts are people who feel they have used energy when interacting socially, rather than gaining energy from social interaction. It's not shyness or anti-social traits.
It will feel like more of a chore for introverts, but it's like a chore you need to do even if it feels bad in the moment, like doing laundry or exercising.
And worse for introverts - people who never invite other people eventually stop getting invited themselves, so to maintain social connection requires introverts to sometimes be the driver of the event.
