Thanks for the PR!

I've noticed that the documentation for this component is incomplete.

• JSDoc is missing (See this comment).
• The name prop is missing in the README.

Could you address these? we can include them in this PR or we can submit a new PR.

Hi @t-hamano,
Since this PR primarily focuses on the Storybook, it would be better to open a separate PR specifically for the component documentation. I’ll work on completing the Storybook here and will open a follow-up PR for the documentation shortly after.
