Corda - how to use CollectSignaturesFlow with AnonymousParty

The CollectSignaturesFlow requires a Collection<FlowSession> where each FlowSession represents the Party you wish to collect a signature from.

You can get a FlowSession using initiateFlow(), however this requires a Party.

How do you collect signatures from AnonymousParty instances?

Context

Within an issuance flow I have a collection of CordaX500Name instances for each participant. I can use these to generate both Party and AnonymousParty instances - this all works fine!

Now I have an amendment flow where I get the previous state, which contains the original collection of AnonymousParty instances. I need to collect signatures from these parties, but as they're anonymous, I can't find a way to do it.

You have to exchange confidential (i.e. anonymous) identities with the counterparty first as part of the flow. See https://docs.corda.net/api-identity.html and the example CorDapp for confidential identities here: https://www.corda.net/samples/.
