Adding Modules to existing campaigns

Hi all, i am trying to add modules to an existing campaign i am running, and all the advice says to use the transmogrifier, but that appears to have vanished.  I may be being an idiot (more than likely) but have i missed something.  I want to put the Princes of the Appocalypse module into my Storm King's Thunder campaign, any help gratefully received :)

What does 'vanished' mean in this context? Was it in that game previously? It should show up for any game that you are the creator (not just GM) of and if it isn't that would be a strange bug that would likely require the  troubleshooting steps.

To use the transmogrifier you first have to do into one of the games you created then click on the setting tab before scrolling all the way down to the bottom. The transmogrifier button is located there. When clicked it will make a popup menu where you will need to select the games you created to get your list of assets to be moved. You just drag and drop from one list to the other.

Thanks guys, i was looking for it in the wrong place, its in the setting within the game itself, not in the settings about the game.  Much appreciated :)
