Open/public group chat

[0xMikado]

I would love to be able to create a group chat fully open/public.

Right now you need to specify which addresses can access the group chat, but it would be nice to be able to create a discussion channel on our website, where any new user can post/read without having an admin that whitelist the address.

Love the idea, we have recently updated our docs to support the same: https://docs-v2.push.org/devs/chat/build/conditional-rules-for-group
