The player who creates the team becomes its leader. In this capacity, they can change certain settings of the team, namely its description, level requirement, avatar and some other.
A leader can appoint one of the team members as their deputy, who enjoys the same privileges. To dothat, a leader must do the following:
Open the Team window and tap on the My Team tab
Tap on any member of the team
Select "Promote to deputy" in the menu that appears.
Like the leader, deputy can aprove or decline applications to join the team from other players.
If the leader decides to leave the team, he must appoint a deputy first.
