What’s a good tool / process to make beta-testers engaged as a community?

Hello, product hunters and creators. I'm starting to have a good plan for acquiring beta testers, but I don't think it's enough. Beta testing is about getting feedback, engaging in real discussion with testers, and ideally creating a community that interacts not only with the makers but also with the testers. So I'm curious if you have anything in mind / that you can share to make testers become active participants together and feel like they are part of a living community 🙏.
