Trying to dynamically set specific Echo for speaking

I am new to NodeRed and I'm trying to setup a flow where the spoken text is directed to the Echo that triggered the NodeRed and external event. The Echo triggers a non NodeRed event which generates a MQTT message which triggers the flow. The flow I have will send the text to the previous Echo that triggered the flow. I tried adding a delay the MQTT flow with no effect.
