I am looking for developer who is well versed with AWS Amplify and able to do the below 1) Include a custom field name " Organization" in the signup tab apart from Username,Password and Email fields * Please note I need Username as Username not email address . 2) Once user signs up they are directed to Confirm Singup page with OTP being sent to their EMAIL address While this kind of simple and easy for some one who is well aquainted with the AWSAmplify working.
