Creating a Team allows you to acquire the following benefits:
Control your workspace data and who can access them: when a user becomes part of a team, they will be able to see only recordings and data related to their activity. On the other hand, a supervisor will be able to see only data of their Team and not the whole Workspace.
Organize your workforce: if your organization has Support and Sales agent, it will be easier to group them within teams so that your Workspace will maintain the same company scheme. Same applies in case you have a multilanguage Support Team: you can create a Team per each language supported by your organization.
This will make it easier to differentiate one from another and to access data and recordings more accurately.
