Multiple Signers in a Role

I have a border line case, let's say there are two signers. One signer signs but do not click confirm. How do you find if signer 1 has completed the signature ceremony or not.

 

I reviewed the signature package JSON, Which i get from getPackage call, and there is no difference between "signature done and not confirmed" state and "signature done and confirmed" state.

 

Question, what is the correct way of finding if any signer has completed signing in case of multiple signers.

I have a scenario in which multiple signers can be part of same role. Like role1 has Signer1, Signer2, and Signer3 When this role1 is linked with Document1 to sign at mentioned location, only Signer1 is getting email to do. Id it possible that all 3 signers in role1 gets email and anyone can do the signing process?
