You are most welcome of course.
I am guessing - and maybe off in a misleading direction - that there is
some kind of configuration in the Mango stuff that looks like a template
that you would set up to send your queries to the map server. For
instance, somewhere you should be specifying things like database
connection parameters or in your case the .qgz file.
Also I wonder if the layer names in the Mango application correspond to the
layer names in QGIS and if not, how you go about setting up that kind of
correspondence. For example, you might have a "streets" layer called
"12345" on the Mango side and "transportation" on the QGIS side.
