How do I edit an avatar's description on an avatar that I've already uploaded?

I made an avatar last year and I want to change/remove the description but I cant seem to do it on the site, in game or even in unity. Is it even possible?

have you tried re-uploading the avatar? that should let you edit the description.

I don’t want to go through the process of re-uploading it, I just want to edit the description
