Getting App variable data in a separate JS file

I get some gro data from an external resourse, placing it in the Server Connect (serverconnect1)

Now I need to process this data in a separate JS file (let’s say, js/map.js).

How can I address this data in this JS file? I tried using dmx.parse, but get errors. And I’m not sure if the App objects sre visible in my custom JS file.
