Auto-Reply to DMs containing certain keywords

Our team asks for ManyChat: https://manychat.com
I think this would be a nice feature for Mixpost.
Manychat allows teams to send customers links via DM, if the customer is sending a certain keyword or emoji via DM. So the workflow:

• Customer sends a banane emoji as DM to the instagram channel of a brand
• The brand auto-replies with a customizable message, often white papers, discount codes or other informations helpful for the customers.

This should help raise interactions.
