Currently all team join invitations are approved from link sent to new member email. This is valid if the email does not have an account with DO.
A new function under My Teams (where I can 'Leave" a team from 3 dots) to include pending approval team join. Team status is already there, but always status is "Joined". I would prefer to stay in DO control panel rather than switch to my email and click a link (that should be not be a phishing email!).
This will be much easier that waiting for the email, sometimes emails have issues (we know, spammers cause alot of trouble causing IPs bans and other delays).
