1 Month after launch, 0 Users so far. What I am doing wrong?

This is not a cheap promotion attempt to get some traffic with a clickbait title. I made a Customer Support app where you can answer customer inquiries directly from Slack workspace. So you don't have to switch between Slack <> Zendesk/Intercom/Whatever you are using. In short, you can handle customer conversations on Slack from beginning to end. These are what I tried for a month after the launch. * Keep writing posts on Thread and Reddit trying to promote the product. * Keep updating new features. But so far, I have no users and I am not even charging the product at this point. :( What am I missing? How do I acquire my first users?
