How do you create swarm/group conversations?

I am able to create a 1 on 1 conversation but I want to create a group chat of 3 users. I cannot figure how how to do this on Android. Can someone please give me step by step instructions on how to do this?

I tried to create a new conversation but cannot find a way to add 2 people to the conversation. I also tried to add another person to a 1 on 1 chat and cannot find a “add” button to do so.

Actually it’s not possible until now.

It’s phase one: Swarm is ready for 1:1 conversation and the next release might be phase 2:
Group chat that allows up to 8 users.

Phase 3 will allow nearly unlimited users.
