Avatars provide 3 different types of avatars: icon avatars, picture avatars, and character avatars
Avatars support two shapes by default: shape, circle, and users can also customize the avatar shape
Avatars support three sizes by default: small, medium, and large, and the user can customize the size
Avatars support character adaptation, which means that when the character length is too long, the avatar automatically adjusts the characters to render the full content
