Getting GameCenter picture URL instead of Texture2D

Im using Unity - Scripting API: GameCenterPlatform in my project right now and Im trying to store the users picture on my server as a url instead of uploading the texture and generating a url myself. I wondering if that is possible, Ive been looking at the docs and not finding much help.

Hi, same issue.
In GooglePlayServices I can take IUserProfile as PlayGamesUserProfile

Then I can get AvatarURL, i dont know how to do this for GameCenter…((
