How can I get BleManager.write-> return promise

Question

Hey I'm new to react :) , trying to get response from write function. I tried the function below.

const response = BleManager.write(
  "XX:XX:XX:XX:XX:XX,
  'XXXXXXXX-0000-XXXX-XXXX-XXXXXXXXXXXX',
  'XXXXXXXX-0000-XXXX-XXXX-XXXXXXXXXXXX',
  data,
  35,
)
  .then(() => {
    console.log(`*******************************Sent ${data}`);
  })
  .catch((error) => {
    console.log(error);
  });

console.log(response);

The result is below: The write function shows the return but can't find where it stores the info.
