Teams can only be created by a Company Administrator.
Creating a Team provides a way to effectively organize users, assign roles, and facilitate collaboration on Projects.
For example, if you are a broadcaster, you could create a team for each Project, assign one or several managers to each of these teams, and let them oversee the other team members.
If you are a Company Administrator or a Team Manager, you should see the Teams section in the top bar under SETTINGS.
You can also access the team's section by clicking on Manage Team inside each Project.
Once in the Teams section, you can click on +Add Team to create a new Team. As a good practice, you should give a name to the new Team.
