I've not done the Maven Central upload stuff before, I'm hoping there's a decent level of validation/authentication/etc around it that someone from the Typesense company may need to do (or maybe its still the wild west like npm hehe just a jab)

In the past, publishing to Maven was a long process (this was a few years ago, so it might have become easier). The alternative is to use Github packages: https://github.com/features/packages
