Hello @mihche ,
Thanks for the solution with rename.
Brief explanation about the project.
1.The users cannot be part of two teams.
2.Group size should be 3 members. If the group filled with 3 members no other users can able to join in the group.
3.If an user already joined in a group he can’t able to create group. If he left that group he can create group.
4. If user created a group he will not able to join different group or create another group.
Thanks,
Raakesh V.
