Read this if you are planning to use a bot account

You can create a bot from @BotFather
The bot must be added to the groups and channels (both source and destination)
The privacy mode of bots should be set to off. That means the bot should be allowed to listen to all messages in the channels/groups it is a member of. By default this setting is on, you have to turn privacy mode off from BotFather.

All sensitive user input in the repl is made invisible to ensure high security.
