[Thread by @mattpocockuk on Thread Reader App – Thread Reader App](https://threadreaderapp.com/thread/1509964736275927042.html)

Why

• Integrate Thread Reader App to unroll the Twitter url

How

• This may be not ideal solution as I searched tweet link on your repo then add below code.

 markdown.push(
      '\n\n' +
        `[Thread by @${user.username} on Thread Reader App – Thread Reader App](https://threadreaderapp.com/thread/${tweet.data.id}.html)`
    )

FYI - I've added those links on my repository as I think Thread Reader App is better UX than Twitter UI jellydn/typescript-tips@8c7dc4f
