MQTT in Vuforia Studio

Hello, I would like to use mqtt in vuforia studio to fetch metadatas from a database hosted on an edge device. I tired different approaches (proxy redirect to "bypass" CORS restrictions, https with a self signed certificate) but at the end of the road I stumble in the same problem: the AR app works on local environment (preview mode) but not on the mobile device (an ipad in this case).
I already made a post about this topic and I've been told that the solution may reside in thingworx and the mqtt extension (which still requires a broker if I'm correct).
I would like to know the detailed steps to achieve mqtt communication in vuforia studio and vuforia view.
Thanks in advance
