Invite links say the role they give
An invite link now names the role it was made for, and disappears once revoked. Your own Macs no longer show up as teammates.
After making an invite link, switching the role picker used to change the line under the link, even though the link still gave the first role. The line now always names the role the link really gives, and the link goes away once you revoke it, so it can no longer be copied by mistake. The people list for your teams also stops counting your own Macs as teammates.
