Adding an admin to a team
Teams also have admins which have the ability to add / remove members, and edit the name and description. To add a member as an admin, click on the button that says "Normal" to the right of the member's avatar in the member list on the team's profile, and select "Admin" in the Change Permissions drop down menu.
On a free team, team admins are able to manage team settings and membership. If you are using a free team and your only admin hast left, see the following steps: Changing the admins of a team or board
On Business Class teams, team admins also have automatic board admin access to team boards.
Set team member permissions to normal or admin.
