Is it possible to use teams api to add member into specific team? I had downloaded the package and successful to send message, but i only can see get and create function.
All Microsoft Teams are backed (or inherit from) an Active Directory group. To add/remove members from a Team, you would use the Add User To Group / Remove User From Group activities.
