I need temporary access to a Telegram bot that can (1) scrape members from public or private groups, then (2) add those users to both my Telegram group and my channel. The bot should run as an easy-to-operate desktop application; I’m comfortable with any authentication method you prefer, as long as setup is quick. Please provide the working bot, short usage instructions, and any limits or best-practice guidelines. I only need the licence for seven consecutive days, so delivery and activation should be immediate once we agree.
