in my experience, it's very hard to start by getting people to come to you. at first, you need to go where people are. if you're someone people enjoy being around (and, in the case of trying to build out a community, someone they feel they can trust for guidance) you'll start to build a small following in each place you spend time
however, if the goal is ego-driven (e.g. "I want people to validate me by adoring me") communities don't tend to thrive
my approach has always been to build communities around a goal. for example, I wanted to experiment with all the tech I saw coming out, and Learn With Jason was a way to do that. people who shared that goal and interest showed up, and it's grown into a great community — but people aren't there because of me specifically
put another way: I don't want fans; I want friends
I think people can sense that and it helps with building out a community
as far as setting up Discord specifically, I haven't done that. someone like Cassidy Williams would know far more about that
