Well the dms guild app you can use to download uses an api and oath key, so I dont see why you can not just add this key in the same way as the steam link... and this is a user giving permission to 'look' at the available downloads/purchases... then its just a matter of having a matching game name on the forge side to auto 'gift' that user a forge key for that extension...
Yes, its still a pain, and might have a bunch of issue as I'm not sure if the dmg guild api is public documented for use etc.....
anyway, we need to get the free extension forge version first... then wait for the paid version.
Im sure nobody cares about 'free extension' on dms guild and having to 're-get' a free version off the Forge etc... Its only paid extensions on dms guild that we need a solution for, and since that is probably many months away until we get paid forge extensions, its less of an issue for now...
