Some share recipient type icons missing

In the screenshots below, I show you that in some cases icons are displayed, and in other cases there are no icons. I don't know if I've covered all the scenarios, but, in my opinion, ALL sharing suggestions should have icons, to make the UX as understandable, pleasant and polished as possible.

Internal shares with user : no single user icon in front of suggested user(s)

Federated share : no federated share representative icon in front of suggested federated user (or group), while there is an icon in front of external e-mail share suggestion

Internal shares with groups have icons
