T-Pose Challenge

Help pls!! My sim has the Admired Icon aspiration and I need to join a T-Pose challenge. I’ve literally never once seen anyone do it and I don’t have an options to start it myself. For real life months I’ve been looking but I got annoyed and switched to a whole different family. Now I’m back playing as her and I still can’t find any way to get it done. Any help would be appreciated, I’ll even cheat it if possible I just want it done. Ty in advance
