Sending UDT's with sparkplug B nodes in Node-Red


We are currently testing out node-red as an interface between OPC UA and MQTT sparkplug B. I am able to subscribe to values from the OPC UA connection, and I am able to connect the sparkplug B nodes to Ignition. However, I am unsure what would be the best practice to connect and send these OPC UA signals via the MQTT sparkplug B nodes utilizing UDT's. I was wondering if anyone had any experience setting up a similar system that maintains dataflow after connection loss and with store and forward working? Would love to hear from you!

It is my understanding that sending UDT's are not yet possible with Node-red
