Example for cases in front end UI conversations

Avatar selection for conversation list.

I need to show an example on how developer can decide which avatar to show in the conversation list row that displays a group conversation.

Group conversations have their own info of the group and avatar/group icon . Sometimes developers will want to show in the OPERATOR side the avatar of the USER and not the group ICON, or maybe a different URL that is defined by developer. The same can happen in the client side, where maybe he wants to see the avatar of the Company (that can be the group icon)
