Team, I am looking for help with below scenarios 1) To add a signer to a transaction, is signer emaild id mandatory in signer json request? 2) What if we have a scenario, where a couple wants to use same email id, but both has to be setup as signers in a transaction? Does each signer should have different email id? 3) Once a Signer is setup and transaction is created, is it possible to change the signer email id? If so, whenever we have to change, do we need to change Transaction status to Draft and update signer info? Thanks for all your help. Thanks, Harry
