implementation? Certainly! Below is an example of how you can implement a React functional component in TypeScript that takes the specified props. This component will render a <div> element that uses the provided size and color props, defaulting to "md" and "blue" respectively if none are provided. The component also renders its children within the <div>.

import React, { ReactNode } from 'react';

interface MyComponentProps {
  size?: 'xs' | 'sm' | 'md' | 'lg';
  color?: 'blue' | 'purple' | 'gray';
  children?: ReactNode;
}

const MyComponent: React.FC<MyComponentProps> = ({
  size = 'md',
  color = 'blue',
  children,
}) => {
  // Example of how you might use the size and color for styling or class names
  const className = `component-${size} component-${color}`;
  
  // Simple implementation of the div with dynamic class names
  return (
    <div className={className}>
      {children}
    </div>
  );
};

export default MyComponent;

In this example, the className is constructed using the size and color props to demonstrate how you might use these props for styling purposes. In a real scenario, you would likely have CSS classes corresponding to each size and color value to apply the desired styles to the component. The children prop is used to render whatever content is passed within the component when it is used.

Here's a quick example of how you might use this component:

<MyComponent size="lg" color="purple">
  <p>This is some content inside the component.</p>
</MyComponent>

This would render a <div> with class names corresponding to "large" and "purple" containing a paragraph of text.How would I put a key on this? {chatHistory.map((message: ChatMessage) => { switch (message.type) { case ChatMessageType.USER_CHAT_MESSAGE: return <ChatTextMessage message={message} />; case ChatMessageType.SYSTEM_RESULTS_KEY: return <SystemResponseMessage message={message} />; } })}
