the logically simple way of making a peer to peer encrypted group chat is just having each member communicate with all the other members, using asymmetric encryption, and each user's endpoint reconstructs the conversation independently. by default each user only sees the parts of the conversation they were actually online for and nobody "owns" the group

but that leads to a potentially awkward situation if the group members don't all agree about who should be in the group. there's no enforcement of membership other than each user agreeing to send messages to X addresses using Y keys

...and it doesn't scale very well. which I think is fine or even good, but should be said
