Not all topics have it! Administrators must actively take part in chat! Otherwise, users simply will not be interested in this project!
It's all about priorities, most often, active communication goes in telegram chats.
Since you started writing about telegram, then it is quite logical to ask a question whether it is planned to create telegram groups?After all, it is really very convenient to have a discussion there.
To be honest I think that channel or group in telegram is rather better, because there are more people there and it can make project even more popular
