Data class representing a single avatar in a StylishConnectedAvatarRow.
Optional URL of an image to display inside the avatar. When null, the initials are shown instead. The image loading is delegated to the caller via the StylishConnectedAvatarRow.avatar slot; the default renderer ignores this field and shows initials.
null
Short text shown inside the avatar when no image is provided, typically a person's initials (max 3 characters are displayed).
