];

const url = "https://api.berri.ai/create_app";
const formData = new URLSearchParams();
formData.append("user_email", "ishaan@berri.ai"); // Replace with your form field and value
formData.append("data_source", JSON.stringify(tmp_list));
fetch(url, {

  body: formData,
})
  .then((response) => response.text())
