How can I pass on a variable value to tweet while posting it?

[giteshsarvaiya]

Using the code under tweets.tweetThread

await rwClient.v2.tweetThread([
  "today's verse",
  { text: `${variableTHA}`},
  //  {text: 'This thread is automatically made with twitter-api-v2 :D'}
]);
  } catch(e) {
    console.error(e);
  }
} catch (error) {
    console.error(error);
}
}

the tweet is showing 'undefined' instead of the value of the variableTha

I want to post dynamically generated texts(originally generated in json fomat, via Another API). How can I perform this task ?
