Sharing Chat History with workspace team

I started a new workspace with my partner. He is added as co-owner and I’ve migrated all of my chat history over to our workspace but he can’t see it yet. How does he get permissions to see the chats? What am I missing

I think this feature isn’t available yet.

New Team account you can’t see old chat history, but can easily toggle to personal account by clicking at bottom-left on my user name, all the history is still there.
