You now have the send, retry and verify otp via following methods.

`javascript
msg91otp.send(contactNumber, args); //args is object of optional parameter

const response = await msg91otp.send(9999999999); // can be passed without country code and as string
console.log(response);

}
`

`javascript
// optional arugemnt object with possible acceptable values
args = {
