- 
avatar_url: string | null
 The URL of the message sender's avatar. Can be nullonly if
the current user has access to the sender's real email address
andclient_gravatarwastrue.
 If null, then the sender has not uploaded an avatar in Zulip,
and the client can compute the gravatar URL by hashing the
sender's email address, which corresponds in this case to their
real email address.
 Changes: Before Zulip 7.0 (feature level 163), access to a
user's real email address was a realm-level setting. As of this
feature level, email_address_visibilityis a user setting.

called "subjects" and will eventually change. For clients that don't support the empty_topic_nameclient capability,
the empty string value is replaced with the value ofrealm_empty_topic_display_namefound in the POST /register response, for channel messages.
