The short answer is:
Be involved in the community, interact with others, help people asking questions. This might not be about you, but people will get to know you.
Share progress on social media. Every time you have something to share, show pictures, screenshots, unfinished content. Every start is slow, keep doing it for a few months, and you will slowly get some people interested.
Participate in jams, at least if can take criticism. People will look at your project and rate it based on others they’ve played.
There’s plenty more ways, but hopefully the ones I mentioned above will help on how to approach the next step.
