How to do Certificate-based authentication in React Native using Rest API?

Hi
I want to do certificate based authentication in React Native, for that I am using Rest API.
And from the docs https://video2.skills-academy.com/en-us/azure/iot-dps/how-to-control-access#certificate-based-authentication I found out this cURL, and I need to send certificate and key file in API, as https.agent is not supported by React Native, how can I manage to do that?

curl -L -i -X PUT –cert ./[device_cert].pem –key ./[device_cert_private_key].pem -H 'Content-Type: application/json' -H 'Content-Encoding:  utf-8' -d '{"registrationId": "[registration_id]"}' https://global.azure-devices-provisioning.net/[ID_Scope]/registrations/[registration_id]/register?api-version=2021-06-01

So far what I have tried is

 const data = {
    registrationId: registrationId,
  };
  const cert = await RNFS.readFile(certificatePath, 'utf8');
  const key = await RNFS.readFile(keyPath, 'utf8');
  console.log('cert', cert);
  console.log('key', key);
  try {
    const httpsAgent = new https.Agent({
      cert: cert,
      key: key,
      keepAlive: true,
    });
    console.log('httpsAgent', httpsAgent);
    const response = await axios({
      method: 'PUT',
      url: `https://global.azure-devices-provisioning.net/${scopeId}/registrations/${registrationId}/register?api-version=2021-06-01`,
      data: data,
      httpsAgent: httpsAgent,
      headers: {
        'Content-Type': 'application/json',
        'Content-Encoding': 'utf-8',
      },
    });
    return response.data;
  } catch (err) {
    console.log('err', err);
    return err;
  }

Thank you!!!
