I'm trying to set up a Flow with a Send and wait for reply widget (triggered with the REST API), however, the reply doesn't seem to trigger the next widget (handle_welcome...) and instead triggers the Incoming Message for the Flow (handle_incoming...).
Is there a way to set up a Flow so that it knows that the received SMS is a reply and not just a generic Incoming Message?
Here is a screenshot of the flow:

I only have one number set up and that is set to trigger the Studio Flow on an incoming message.
Also, I'm not sure if it makes a difference but I have Concurrent calls trigger enabled.
