MQTT Message Handling Flow

This workflow is designed to demonstrate the capabilities of MQTT tools for subscribing and publishing messages. It begins with a Start node that accepts an MQTT payload as input. The flow then branches into two paths: one path involves a 'Sleep 5s' code node, which introduces a delay to ensure that subscription processes are completed before proceeding. This path leads to an 'MQTT Subscribe' tool node, which subscribes to messages from the topic 'dify/#'. The other path directly connects to an 'MQTT Publish' tool node, which publishes the provided payload to the topic 'dify/test'. Finally, both paths converge at an End node that outputs the data received from the subscription process.
