Identify and open the User
To add an existing user to an existing Team, first, conduct a search (1) for the User and open the User profile (2).
Select a Role
On the User profile, Teams that the User is not already a member of will appear below the line. Select a Role on your Team for the User by clicking the dropdown (3).
Finally, click Save (4).
NOTE: If a User has access to two teams with the same Project, but has a different Team Access level on the teams, their capabilities will default to the highest level of access.
