How to delete deprecated products from Indie Hackers Profile?

I was earlier working on a couple of products (prior to 2019) and the products no longer exist. I no longer own the websites for these products and they are now owned by others. I would like to remove them from IH directory (as well as my profile), however I couldn't find a way to remove them. I sent emails to the IH team however didn't receive any response. Can someone help me remove these products from IH directory ?
