Each one logs in over MTProto (`auth.importBotAuthorization`, the same door a bot-login client uses), backfills the history of the bot's dialogs once and then keeps the incoming stream: who writes to the bot, what, and when. A separate authorization, so it does not take `getUpdates` away from whoever runs that bot over the Bot API.
