Great progress, Pawan! Could you please add some Storybook stories as we've done with other components? This is the recommended way to develop these in isolation for quick dev and to be able to demo them.

Hey Pawan, thanks for adding the Storybook and other updates!

Based on the Storybook, things don't quite match designs yet. I think we need some more changes here to make this helpful for devs.

Some things to note or think about:

1. Title text doesn't match
2. Padding is too small
3. To provide value, we may want to add some other things based on our sample designs that build behavior in for developers such as:

• a subtitle prop that has opinionated styling within the component
• a way to add buttons (that conforms to designs)

Let me know if you have any questions!
