  const contextValue = React.useMemo(() => ({
    backgrounds: ['#000000', '#DD2C00', '#6200EA', '#3F51B5'], // Any props used by Avatar can be used here.
  }), []);
  return (
    <AvatarContext.Provider>
      <div style={{ display: 'flex' }}>
        <Avatar
          htmlWidth='150px'
          text="Fallback"
          backgrounds={['red']}
          textColor='white'
        />
        <Avatar
          htmlWidth='150px'
          text="AJ"
