Already have a bot on another platform and want to transfer its subscribers over to ManyChat? Here's a workaround for it:
1. Connect ManyChat to the Facebook page that has your other bot connected to it.
2. Send a broadcast with a Button to all your subscribers via the first bot.
3. Everyone who interacts with the broadcast will appear in your ManyChat account as a new subscriber.
4. Now you're free to reach out to your previous bot's audience through ManyChat! :)
