Where are my downloaded teleporter files?

I recently downloaded 2 teleporters from the Sims Exchange but now I can't find it in my game. I know there's a teleporter that's a hidden object that you get with lifetime rewards however these are regular downloaded versions from the sims exchange. Both of the ones I downloaded are compatible with my expansions & it shows that they are installed. However I can't find where any of these items are. I've looked through every room, every item grouping  in both buy & build mode & cannot find my downloaded teleporters. f anyone has an answer to this please let me know. Thank you!
