I cannot find my addons

I'm not sure if this is the right place to post this, but I've been gifted The Forge of Fury, The Sunless Citadel, Dead in Thay, Against the Giants, White Plume Mountain, Hidden Shrine of Tamoachan, and Tomb of Horrors. But I can't find them anywhere, this is the first time I've been gifted something and the wiki didn't help.  Any assistance would be very much appreciated.

Hi, Matita . The How to Access Marketplace Content section of the Wiki has a section on Game Addons . Hopefully, that section will prove more helpful than the parts of the Wiki you may have already seen. If not, please let us know so we can assist further! Thanks!

Oh they're add ons  not modules that might help a little more haha, thank you very much I'll probably find my answer there < 3.
