Send Delayed Twilio SMS using Redis for State

## Try It Out!
### This workflow demonstrates a simple approach to stagger an AI Agent's reply if users often send in a sequence of partial messages and in short bursts.

* Twilio webhook receives user's messages which are recorded in a message stack powered by Redis.
* The execution is immediately paused for 5 seconds and then another check is done against the message stack for the latest message.
* The purpose of this check lets use know if the user is sending more messages or if they are waiting for a reply.
* The execution is aborted if the latest message on the stack differs from the incoming message and continues if they are the same.
* For the latter, the agent receives buffered messages and is able to respond to all in a single reply.
