Per this link https://community.telligent.com/community/10/w/api-documentation/60298/forum-widget-api-supplementary-type we can access a Forum Applications `AvatarUrl`.
However I'm unable to locate where these images are uploaded.
Is this property not defined by an Administrator upload via Admin Panel? How can we populate the `forum-widget-api-supplementary-type.AvatarUrl` property?
