Avatars can't be used with SSO sign in

Please give a quick overview of your product feature request or feedback and note who in your org is affected by this issue [ex. agents, admins, customers, etc.]. (2-3 sentences)

Since we utilize SSO, I would like customer's to have the ability to set their own avatar with Zendesk Gather. This feature is currently affecting my agents because they aren't able to set this on their own.

What problem do you see this solving? (1-2 sentences) 

As our Community Manager put it "this just makes our entire page gray, with gray faceless circles next to each username."

When was the last time you were affected by this lack of functionality, or specific tool? What happened? How often does this problem occur and how does this impact your business? (3-4 sentences)

Prior to moving to Gather we utilized XenForo which had this option. Customer's like being able to set their own avatar and not having that is seen as a negative since moving to Gather.

Are you currently using a workaround to solve this problem? (If yes, please explain) (1-2 sentences)

No.

What would be your ideal solution to this problem? How would it work or function? (1-2 sentences)

The ideal solution would be to allow the option for customer's to upload their avatar even if the Zendesk instance is using SSO. We can try to tie in setting the avatar in SSO, but the experience would be much better if Zendesk could handle this natively.
