• We will add lookup capability to Register API for username -> Party ID, but this will take some time
• In the meantime, do they have the party ID? If so they can use the party ID directly

[martinothamar]

We agreed that we will find a manual workaround until register API is ready. There were not a lot of parties so we will do the mapping offline
