9. How to Adjust External Share Settings
1. To add someone to a conversation, or to adjust the permissions, go to the top right of the conversation and hit 'Channel Access' (the folder icon).
2. From Manage Settings, you can see who has access to this conversation and when they last viewed it. You can also toggle permissions, chat expirations, or end the chat.
3. If you'd like to, you can also invite individuals from this modal. Switch to the Invite People tab to add their email addresses and a note.
