Choose Members to see everyone in the group, then Add People to bring in more — search by name and select who to add.
Admins: remove members and promote others
In the Members list, group admins have extra controls: remove a member, or make someone an admin so they can help manage the group too.
Leave a group
Choose Leave Group to remove yourself from the conversation. You’ll stop receiving its messages.
Direct messages are different: These controls apply to group chats and property threads. A one‑on‑one direct message has no members list, name, or photo to manage.
