Hello, I am studying the wallet functionality from here. I can see that the user Isabella can have multiple identities so I understand that in the chaincode I can verify not only the user but the identity (e.g ID1, ID2) of the user too (who invoked the transaction). Therefore, my questions are:
1) Is there any code sample that does that verification inside the chaincode?
2) How can select from my client application a specific ID from the wallet in order to invoke the transaction? (eg. ID1)

Thanks,
