Have you had a look at [node-red-contrib-simple-message-queue (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-simple-message-queue)
> A simple queue node that stores incoming messages in a memory queue and uses a feedback from a following action or trigger message to release the next message stored in the queue
