MQTT Docs need to be updated?

I am following the MQTT work at MQTT | Meshtastic and at “Using MQTT with Node-Red” section and you call out using GitHub - meshtastic/protobufs: Protobuf definitions for the Meshtastic project inside Node-Red, howver it doesn’t work and according to the GitHub - meshtastic/protobufs: Protobuf definitions for the Meshtastic project team, this is not supported in Node-Red.

So what gives???
