The Team plan allows for 5 total members: 1 owner and 4 additional team members. The person who purchases the Team plan is the Team owner. The Team owner is able to add 4 other Team members who can create and edit prototypes in the Team account.
Team members can:
Create prototypes (unlike collaborators)
Edit and inspect prototypes
Add, replace, or delete screens
Add or remove hotspots
Once a person is added to the Team account, they’ll be prompted to transfer prototypes from their personal account to the Team account. Prototypes can also be manually transferred.
The Team member maintains their own personal account. However, any prototypes created in or transferred to the Team account belong to the Team owner.
When Team members create new prototypes, they’ll be able to select whether they want that project to live in the Team account or in their personal account. The Team account is selected by default. To learn more, check out this article: How do I create a prototype on a Team plan?
