I am trying to connect an ignition edge client to a central server through MQTT. I can’t find any information anywhere on how to do so.

I have both the server and the edge gateway up and going. I have the MQTT distributor and engine going in the server. Do I need another license on the edge to connect through MQTT also? The edge platform I am using is edge-mqtt so I figured I didn’t need another license but I could be wrong.

I assume there is somewhere that I type in the host address but I can’t seem to find that.
