Fork chats help you start a new conversation from an existing one (1-1, Group Chat, Channel). You can choose how many users you want to share the chat with and from which point you want to share it.
To fork your chat:
Select users by name or email address in the "Add users to fork chat pop-up" that appears, now give the chat a title and click Create.
If you don't want to include the existing chat's participants, uncheck the box that says 'Include all participants of this conversation.'

The new forked chat will be a standalone chat, meaning that any changes made to the old chat will not be reflected in the new forked chat.
