Unable to delete EA featured gallery creation

In 2020, when I was a minor, I uploaded a household to the Sims 4 gallery that somehow was selected for the Spark’d Challenges / Spark’d Destination showcase.

At the time the household was created and uploaded, I was a minor, and I am no longer comfortable having this content publicly featured or associated with my profile. But because the item appears to be locked as a curated or featured upload, I no longer have the option to delete or unshare it myself through the Gallery. I was told to report it but was unable to find a flag button, and I was referred to these forums by EA help.

I would greatly appreciate assistance removing this upload from public showcase listings and my Gallery profile.
