Hello Boss,
Got it, I can make python script that will work as you want. using command "/active" and see all the active workers (If a user have send a message in the last 10 minutes, he will be an active user in the channel). Message "active users: [number]" and the second line, the list of all active users by @name and chat ID. I can start to work in your project immediately. Please contact me, So we can discuss more over chat.
