Shared content for modules

Hi, 

A friend of mine who owns a module (the Planescape one and Vecna) would like me to run it for our group. Is there any way for me to gain access to it the via them sharing it, preferably in the maps vtt?

The other guy in our group has the master tier sub; but when I go into the group and try to launch the vtt it forces me to be a player not the dm. Is there any way for me to DM on the map to VTT?

I'll try that next, thank you. As a test I have had bought nest of the Eldritch eye and tried looking at that and maps but none of the monsters were placed on the map. Did I just load it wrong or does the maps vtt version of modules generally not have the monsters pre-placed?

Well that's incredibly frustrating, and even mildly infuriating. But thank you for the info.
